TPS768xxQ www.ti.com SLVS211L–JUNE1999–REVISEDJANUARY2006 APPLICATION INFORMATION The TPS768xxQ family includes eight fixed-output voltage regulators (1.5 V, 1.8 V, 2.5 V, 2.7 V, 2.8 V, 3.0 V, 3.3V,and5.0V),andoffersanadjustabledevice,theTPS76801(adjustablefrom1.2Vto5.5V). DEVICE OPERATION The TPS768xxQ features very low quiescent current, which remains virtually constant even with varying loads. Conventional LDO regulators use a PNP pass element, the base current of which is directly proportional to the load current through the regulator (I = I /b ). The TPS768xxQ uses a PMOS transistor to pass current; because B C thegateofthePMOSisvoltagedriven,operatingcurrentislowandinvariableoverthefullloadrange. Another pitfall associated with the PNP-pass element is its tendency to saturate when the device goes into dropout. The resulting drop in b forces an increase in I to maintain the load. During power up, this translates to B large start-up currents. Systems with limited supply current may fail to start up. In battery-powered systems, it means rapid battery discharge when the voltage decays below the minimum required for regulation. The TPS768xxQquiescentcurrentremainslowevenwhentheregulatordropsout,eliminatingbothproblems. The TPS768xxQ family also features a shutdown mode that places the output in the high-impedance state (essentially equal to the feedback-divider resistance) and reduces quiescent current to 2 m A. If the shutdown featureisnotused,ENshouldbetiedtoground. MINIMUM LOAD REQUIREMENTS TheTPS768xxQfamilyisstableevenatzeroload;nominimumloadisrequiredforoperation. FB - PIN CONNECTION (ADJUSTABLE VERSION ONLY) The FB pin is an input pin to sense the output voltage and close the loop for the adjustable option. The output voltage is sensed through a resistor divider network to close the loop as shown in Figure 27. Normally, this connection should be as short as possible; however, the connection can be made near a critical circuit to improve performance at that point. Internally, FB connects to a high-impedance wide-bandwidth amplifier and noise pickup feeds through to the regulator output. Routing the FB connection to minimize/avoid noise pickup is essential. EXTERNAL CAPACITOR REQUIREMENTS An input capacitor is not usually required; however, a ceramic bypass capacitor (0.047 m F or larger) improves load transient response and noise rejection if the TPS768xxQ is located more than a few inches from the power supply. A higher-capacitance electrolytic capacitor may be necessary if large (hundreds of milliamps) load transientswithfastrisetimesareanticipated. Like all low dropout regulators, the TPS768xxQ requires an output capacitor connected between OUT and GND to stabilize the internal control loop. The minimum recommended capacitance value is 10 m F and the ESR (equivalent series resistance) must be between 60 mW and 1.5 W . Capacitor values 10 m F or larger are acceptable, provided the ESR is less than 1.5W . Solid tantalum electrolytic, aluminum electrolytic, and multilayer ceramiccapacitorsareallsuitable,providedtheymeettherequirementsdescribedabove. SubmitDocumentationFeedback 11

The internal comparator monitors the output voltage: when the output drops to between 92% and 98% of its nominal regulated value, the PG output transistor turns on, taking the signal low. The open-drain output requires a pullup resistor. If not used, it can be left floating. PG can be used to drive power-on reset circuitry or used as a low-battery indicator. PG does not assert itself when the regulated output voltage falls out of the specified 2% tolerance,butinsteadreportsanoutputvoltagelow,relativetoitsnominalregulatedvalue. 12 SubmitDocumentationFeedback

TPS768xxQ www.ti.com SLVS211L–JUNE1999–REVISEDJANUARY2006 APPLICATION INFORMATION (continued) REGULATOR PROTECTION The TPS768xxQ PMOS-pass transistor has a built-in back diode that conducts reverse currents when the input voltage drops below the output voltage (for example, during power-down). Current is conducted from the output to the input and is not internally limited. When extended reverse voltage is anticipated, external limiting may be appropriate. The TPS768xxQ also features internal current limiting and thermal protection. During normal operation, the TPS768xxQ limits output current to approximately 1.7 A. When current limiting engages, the output voltage scales back linearly until the overcurrent condition ends. While current limiting is designed to prevent gross device failure, care should be taken not to exceed the power dissipation ratings of the package. If the temperature of the device exceeds +150(cid:176) C (typ), thermal-protection circuitry shuts it down. Once the device has cooledbelow+130(cid:176) C(typ),regulatoroperationresumes. POWER DISSIPATION AND JUNCTION TEMPERATURE Specified regulator operation is assured to a junction temperature of +125(cid:176) C; the maximum junction temperature should be restricted to +125(cid:176) C under normal operating conditions. This restriction limits the power dissipation the regulator can handle in any given application. To ensure the junction temperature is within acceptable limits, calculate the maximum allowable dissipation, P max, and the actual dissipation, P , which must be less than or D D equaltoP max.
