The Enable On/Off threshold has no hysteresis. The voltage signal must rise and fall cleanly, and promptly, through the ON and OFF voltage thresholds. The EN pin voltage must be higher than the V threshold to EN(MIN) ensure that the device is fully enabled under all operating conditions. The EN pin voltage must be lower than the V threshold to ensure that the device is fully disabled. The EN pin has no internal pullup or pulldown to EN(MAX) establish a default condition and, as a result, this pin must be terminated either actively or passively. If the EN pin is driven from a source that actively pulls high and low, the drive voltage must not be allowed to go below ground potential or higher than V . If the application does not require the Enable function, the pin must be IN connecteddirectlytotheINpin. 8.3.2 ThermalOverloadProtection(T ) SD Thermal Shutdown disables the output when the junction temperature rises to approximately 160°C which allows thedevicetocool.Whenthejunctiontemperaturecoolstoapproximately150°C,theoutputcircuitryenables. Based on power dissipation, thermal resistance, and ambient temperature, the thermal protection circuit may cycle on and off. This thermal cycling limits the dissipation of the regulator and protects it from damage as a result of overheating. The Thermal Shutdown circuitry of the LP38693 has been designed to protect against temporarythermaloverloadconditions. The Thermal Shutdown circuitry was not intended to replace proper heat-sinking. Continuously running the LP38693deviceintothermalshutdowndegradesdevicereliability. 8.3.3 FoldbackCurrentLimiting Foldback current limiting is built into the LP38691 and LP38693 devices which reduces the amount of output current the part can deliver as the output voltage is reduced. The amount of load current is dependent on the differential voltage between the IN and OUT pins. Typically, when this differential voltage exceeds 5 V, the load current limits at about 350 mA. When the V – V differential is reduced below 4 V, load current is limited to IN OUT about850mA. CAUTION When toggling the LP38693 Enable (EN) after the input voltage (V ) is applied, the IN foldback current limit circuitry is functional the first time that the EN pin is taken high. The foldback current limit circuitry is non-functional the second, and subsequent, times that the EN pin is taken high. Depending on the input and output capacitance values the input inrush current may be higher than expected which can cause the input voltagetodroop. If the EN pin is connected to the IN pin, the foldback current limit circuitry is functional whenV isappliedifV startsfromlessthan0.4V. IN IN 8.4 Device Functional Modes 8.4.1 Enable(EN) The EN pin voltage must be higher than the V threshold to ensure that the device is fully enabled under all EN(MIN) operatingconditions. 8.4.2 MinimumOperatingInputVoltage(V ) IN The LP38691 and LP38693 do not include any dedicated UVLO circuitry. Neither device internal circuitry is fully functional until V is at least 2.7 V. The output voltage is not regulated until V ≥ (V + V ), or 2.7 V, IN IN OUT DO whicheverishigher.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information 9.1.1 ReverseVoltage A reverse voltage condition exists when the voltage at the output pin is higher than the voltage at the input pin. Typically this happens when V is abruptly taken low and C continues to hold a sufficient charge such that IN OUT the input to output voltage becomes reversed. A less common condition is when an alternate voltage source is connectedtotheoutput. TherearetwopossiblepathsforcurrenttoflowfromtheOUTpinbacktoINduringareversevoltagecondition. 1. While V is high enough to keep the control circuity alive, and the EN pin (LP38693 only) is above the IN V threshold, the control circuitry attempts to regulate the output voltage. If the input voltage is less than EN(ON) the programmed output voltage, the control circuit drives the gate of the pass element to the full ON condition. In this condition, reverse current flows from the OUT to the IN pin, limited only by the R of DS(ON) the pass element and the output to input voltage differential. Discharging an output capacitor up to 1000 μF in this manner does not damage the device as the current rapidly decays. However, continuous reverse currentmustbeavoided.WhentheENpinislow,thisconditionisprevented. 2. The internal PFET pass element has an inherent parasitic diode. During normal operation, the input voltage is higher than the output voltage and the parasitic diode is reverse biased. However, when V is below the IN value where the control circuity is alive, or the EN pin is low (LP38693 only), and the output voltage is more than 500 mV (typical) above the input voltage the parasitic diode becomes forward biased and current flows from the output pin to the input pin through the diode. The current in the parasitic diode must be limited to lessthan1-Acontinuousand5-Apeak. If used in a dual-supply system where the regulator output load is returned to a negative supply, the output pin must be diode-clamped to ground to limit the negative voltage transition. A Schottky diode is recommendedforthisprotectiveclamp. 9.2 Typical Application VIN VOUT VIN VOUT IN OUT IN OUT LP38691 EN LP38693 ** V ** SNS EN SNS 1 µF * GND 1 µF * 1 µF * GND 1 µF * *Minimumvaluerequiredforstability. **WSONpackagedevicesonly. 14 SubmitDocumentationFeedback Copyright©2005–2015,TexasInstrumentsIncorporated ProductFolderLinks:LP38691 LP38693 LP38691-Q1 LP38693-Q1

Thus, the power dissipation is dependent on the ambient temperature and the thermal resistance across the various interfaces betweenthediejunctionandambientair.

These two equationsmustbeusedtodeterminetheoptimumoperatingconditionsforthedeviceintheapplication.

A-MAX In applications where high power dissipation and/or poor package thermal resistance is present, the maximum ambient temperature (T ) may have to be derated. T is dependent on the maximum operating junction A-MAX A-MAX temperature (T = 125°C), the maximum allowable power dissipation in the device package in the J-MAX-OP application (P ), and the junction-to ambient thermal resistance of the part/package in the application (R ), D-MAX θJA asgivenbyEquation3: T =(T –(R ×P )) (3) A-MAX J-MAX-OP θJA D-MAX Alternately, if T can not be derated, the P value must be reduced. This can be accomplished by reducing A-MAX D V in the V – V term as long as the minimum V is met, or by reducing the I term, or by some IN IN OUT IN OUT combinationofthetwo. 9.2.2.2 ExternalCapacitors In common with most regulators, the LP38691 and LP38693 require an external capacitors for regulator stability. The devices are specifically designed for portable applications requiring minimum board space and smallest components.Thesecapacitorsmustbecorrectlyselectedforgoodperformance. 9.2.2.3 InputCapacitor An input capacitor is required for stability. TI recommends that a 1-µF capacitor be connected between the devices'INpinandGNDpin(thiscapacitancevaluemaybeincreasedwithoutlimit).

LP38691,LP38693,LP38691-Q1,LP38693-Q1 SNVS321O–JANUARY2005–REVISEDDECEMBER2015 www.ti.com Important: To ensure stable operation it is essential that good PCB design practices are employed to minimize ground impedance and keep input inductance low. If these conditions cannot be met, or if long leads are used to connect the battery or other power source to the LP38691 or LP38693, then TI recommends that the input capacitor is increased. Also, tantalum capacitors can suffer catastrophic failures due to surge current when connectedtoalow-impedancesourceofpower(likeabatteryoraverylargecapacitor).Ifatantalumcapacitoris used at the input, it must be ensured by the manufacturer to have a surge current rating sufficient for the application. There are no requirements for the equivalent series resistance (ESR) on the input capacitor, but tolerance and temperature coefficient must be considered when selecting the capacitor to ensure the capacitance remains approximately1 µFovertheentireoperatingtemperaturerange. 9.2.2.4 OutputCapacitor The LP3869x is designed specifically to work with very small ceramic output capacitors. A 1-µF ceramic capacitor (temperature types Z5U, Y5V or X7R/X5R) with ESR between 5 mΩ to 500 mΩ, is suitable in the LP3869xapplicationcircuit. ForthisdevicetheoutputcapacitormustbeconnectedbetweentheOUTpinandGNDpin. It is also possible to use tantalum or film capacitors at the device output, but these are not as attractive for reasonsofsizeandcost. The output capacitor must meet the requirement for the minimum value of capacitance and also have an ESR valuethatiswithintherange5mΩ to500mΩ forstability. 9.2.2.5 No-LoadStability The LP3869x remains stable and in regulation with no external load. This is an important consideration in some circuits,forexampleCMOSRAMkeep-aliveapplications. 9.2.2.6 CapacitorCharacteristics The LP3869x is designed to work with ceramic capacitors on the output to take advantage of the benefits they offer. For capacitance values in the range of 0.47 µF to 4.7 µF, ceramic capacitors are the smallest, least expensive and have the lowest ESR values, thus making them best for eliminating high frequency noise. The ESR of a typical 1-µF ceramic capacitor is in the range of 20 mΩ to 40 mΩ, which easily meets the ESR requirementforstabilityfortheLP3869x. For both input and output capacitors, careful interpretation of the capacitor specification is required to ensure correct device operation. The capacitor value can change greatly, depending on the operating conditions and capacitortype. In particular, the output capacitor selection must take account of all the capacitor parameters, to ensure that the specification is met within the application. The capacitance can vary with DC bias conditions as well as temperature and frequency of operation. Capacitor values also show some decrease over time due to aging. The capacitor parameters are also dependent on the particular case size, with smaller sizes giving poorer performance figures in general. As an example, Figure 27 shows a typical graph comparing different capacitor casesizesinaCapacitancevs.DCBiasplot.Asshowninthegraph,increasingtheDCBiasconditioncanresult in the capacitance value falling below the minimum value given in the recommended capacitor specifications table (0.7 µF in this case).

TypicalVariationInCapacitancevsDCBias The value of the ceramic capacitor can vary with temperature. The capacitor type X7R, which operates over a temperature range of –55°C to 125°C, only varies the capacitance to within ±15%. The capacitor type X5R has a similar tolerance over a reduced temperature range of –55°C to 85°C. Many large value ceramic capacitors, larger than 1 µF, are manufactured with Z5U or Y5V temperature characteristics. Their capacitance can drop by more than 50% as the temperature varies from 25°C to 85°C. Therefore, X7R and X5R types are recommended overZ5UandY5Vinapplicationswheretheambienttemperaturechangessignificantlyaboveorbelow25°C. Tantalum capacitors are less desirable than ceramic for use as output capacitors because they are more costly whencomparingequivalentcapacitanceandvoltageratingsinthe0.47-µFto4.7-µFrange. Another important consideration is that tantalum capacitors have higher ESR values than equivalent size ceramics. This means that while it may be possible to find a tantalum capacitor with an ESR value within the stable range, it would have to be larger in capacitance (which means bigger and more costly) than a ceramic capacitor with the same ESR value. It mustalso be noted that the ESR of a typical tantalum increases about 2:1 asthetemperaturegoesfrom25°Cdownto –40°C,sosomeguardbandmustbeallowed. 9.2.2.7 RFI/EMISusceptibility Radio frequency interference (RFI) and electromagnetic interference (EMI) can degrade any integrated circuit’s performance because of the small dimensions of the geometries inside the device. In applications where circuit sources are present which generate signals with significant high frequency energy content (> 1 MHz), care must betakentoensurethatthisdoesnotaffectthedeviceregulator. If RFI/EMI noise is present on the input side of the regulator (such as applications where the input source comes from the output of a switching regulator), good ceramic bypass capacitors must be used at the input pin of the device. If a load is connected to the device output which switches at high speed (such as a clock), the high-frequency current pulses required by the load must be supplied by the capacitors on the IC output. Because the bandwidth of the regulator loop is less than 100 kHz, the control circuitry cannot respond to load changes above that frequency. This means the effective output impedance of the device at frequencies above 100 kHz is determined onlybytheoutputcapacitors. In applications where the load is switching at high speed, the output of the IC may need RF isolation from the load. TI recommends that some inductance be placed between the output capacitor and the load, and good RF bypasscapacitorsbeplaceddirectlyacrosstheload. PCB layout is also critical in high noise environments, because RFI/EMI is easily radiated directly into PC traces. Noisy circuitry must be isolated from clean circuits where possible, and grounded through a separate path. At MHz frequencies, ground planes begin to look inductive and RFI/ EMI can cause ground bounce across the ground plane. In multi-layer PCB applications, care must be taken in layout so that noisy power and ground planesdonotradiatedirectlyintoadjacentlayerswhichcarryanalogpowerandground.

Total Output Noise or Broad-Band Noise is the RMS sum ofspotnoiseoveraspecifiedbandwidth,usuallyseveraldecadesoffrequencies. Attention paid to the units of measurement. Spot noise is measured in units µV√Hz or nV√Hz, and total output noiseismeasuredinµV . RMS The primary source of noise in low-dropout regulators is the internal reference. Noise can be reduced in two ways: by increasing the transistor area or by increasing the current drawn by the internal reference. Increasing the area decreases the chance of fitting the die into a smaller package.

The input supply must be well regulated and free of spurious noise. To ensure that the device output voltage is well regulated, input supply must be at least V + 0.5 V, or 2.7 V, whichever is higher.

PCB layout practices that are adequate for typical LDOs may degrade the load regulation, PSRR, noise, or transient performanceoftheLP38691orLP38693. Best performance is achieved by placing C and C on the same side of the PCB as the LP38691 or IN OUT LP38693, and as close to the package as is practical. The ground connections for C and C must be back to IN OUT theLP38691orLP38693GNDpinusingaswide,andasshort,acoppertraceasispractical.

PACKAGE OPTION ADDENDUM www.ti.com 6-Nov-2018 (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
