They accept up to 35 V of input voltage and with proper heat dissipation can provide over 1.5 A of current. With a combination of current limiting, thermal shutdown, and safe area protection, these regulators eliminate any concern of damage. These features paired with excellent line and load regulation make the LM340 and LM7805 Family versatile solutions to a wide range of power management designs. Although the LM340 and LM7805 Family were designed primarily as fixed-voltage regulators, these devices can be used with external componentforadjustablevoltageandcurrent. 7.2 Functional Block Diagram 7.3 Feature Description 7.3.1 OutputCurrent With proper considerations, the LM340 and LM7805 Family can exceed 1.5-A output current. Depending on the desired package option, the effective junction-to-ambient thermal resistance can be reduced through heat sinking,allowingmorepowertobedissipatedinthedevice. 7.3.2 CurrentLimitingFeature In the event of a short circuit at the output of the regulator, each device has an internal current limit to protect it fromdamage.ThetypicalcurrentlimitsfortheLM340andLM7805Familyis2.4A. 7.3.3 ThermalShutdown Each package type employs internal current limiting and thermal shutdown to provide safe operation area protection.Ifthejunctiontemperatureisallowedtoriseto150°C,thedevicewillgointothermalshutdown. 7.4 Device Functional Modes Therearenofunctionalmodesforthisdevice. 12 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LM340 LM340A LM7805 LM7812 LM7815

LM340,LM340A,LM7805,LM7812,LM7815 www.ti.com SNOSBT0L–FEBRUARY2000–REVISEDSEPTEMBER2016 8 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 8.1 Application Information The LM340x and LM7805 series is designed with thermal protection, output short-circuit protection, and output transistor safe area protection. However, as with any IC regulator, it becomes necessary to take precautions to assure that the regulator is not inadvertently damaged. The following describes possible misapplications and methodstopreventdamagetotheregulator. 8.1.1 ShortingtheRegulatorInput When using large capacitors at the output of these regulators, a protection diode connected input to output (Figure 15) may be required if the input is shorted to ground. Without the protection diode, an input short causes the input to rapidly approach ground potential, while the output remains near the initial V because of the OUT stored charge in the large output capacitor. The capacitor will then discharge through a large internal input to output diode and parasitic transistors. If the energy released by the capacitor is large enough, this diode, low current metal, and the regulator are destroyed. The fast diode in Figure 15 shunts most of the capacitors dischargecurrentaroundtheregulator.Generally no protection diode is required for values of output capacitance ≤10 μF. 8.1.2 RaisingtheOutputVoltageAbovetheInputVoltage Because the output of the device does not sink current, forcing the output high can cause damage to internal low currentpathsinamannersimilartothatjustdescribedinShortingtheRegulatorInput. 8.1.3 RegulatorFloatingGround When the ground pin alone becomes disconnected, the output approaches the unregulated input, causing possible damage to other circuits connected to V . If ground is reconnected with power ON, damage may also OUT occur to the regulator. This fault is most likely to occur when plugging in regulators or modules with on card regulators into powered up sockets. The power must be turned off first, the thermal limit ceases operating, or the groundmustbeconnectedfirstifpowermustbelefton.SeeFigure16. 8.1.4 TransientVoltages If transients exceed the maximum rated input voltage of the device, or reach more than 0.8 V below ground and have sufficient energy, they will damage the regulator. The solution is to use a large input capacitor, a series inputbreakdowndiode,achoke,atransientsuppressororacombinationofthese. Figure15.

Figure18. FixedOutputVoltageRegulator 8.2.1.1 DesignRequirements The device component count is very minimal. Although not required, TI recommends employing bypass capacitors at the output for optimum stability and transient response. These capacitors must be placed as close as possible to the regulator. If the device is located more than 6 inches from the power supply filter, it is required toemployinputcapacitor. 14 SubmitDocumentationFeedback Copyright©2000–2016,TexasInstrumentsIncorporated ProductFolderLinks:LM340 LM340A LM7805 LM7812 LM7815

LM340,LM340A,LM7805,LM7812,LM7815 www.ti.com SNOSBT0L–FEBRUARY2000–REVISEDSEPTEMBER2016 9 Power Supply Recommendations The LM340 is designed to operate from a wide input voltage up to 35 V. Please refer to electrical characteristics tables for the minimum input voltage required for line/load regulation. If the device is more than six inches from theinputfiltercapacitors,aninputbypasscapacitor,0.1 μForgreater,ofanytypeisneededforstability. 10 Layout 10.1 Layout Guidelines Some layout guidelines must be followed to ensure proper regulation of the output voltage with minimum noise. Traces carrying the load current must be wide to reduce the amount of parasitic trace inductance. To improve PSRR, a bypass capacitor can be placed at the OUTPUT pin and must be placed as close as possible to the IC. All that is required for the typical fixed output regulator application circuit is the LM340x/LM7805 Family IC and a 0.22-µF input capacitor if the regulator is placed far from the power supply filter. A 0.1-µF output capacitor is recommended to help with transient response. In cases when VIN shorts to ground, an external diode must be placedfromVOUTtoVINtodivertthesurgecurrentfromtheoutputcapacitorandprotecttheIC. 10.2 Layout Example Figure27.

PACKAGE OPTION ADDENDUM www.ti.com 6-Feb-2020 (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.
