ULTRALOW-POWER SC70/SOT-323 PACKAGED 10 mA LDO LINEAR REGULATORS WITH POWER GOOD OUTPUT
FEATURES D 10-mA Low-Dropout Regulator D Ultralow 1.2-µA Quiescent Current at 10 mA D 5-Pin SC70/SOT-323 (DCK) Package D Integrated Power Good Output D Stable With Any Capacitor (>0.47 µF) D Dropout Voltage Typically 105 mV at 10 mA D D
(TPS79733) Over Current Limitation ­40°C to 85°C Operating Junction Temperature Range element. Because the PMOS pass element behaves as a low-value resistor, the dropout voltage is very low, typically 105 mV at 10 mA of load current, and is directly proportional to the load current. The quiescent current is ultralow (1.2 µA typically) and is stable over the entire range of output load current (0 mA to 10 mA). When properly configured with a pullup resistor, the PG output can be used to implement a power-on reset or low battery indicator. The TPS797xx is offered in 1.8-V, 3-V, 3.3-V fixed options.

DESCRIPTION
The TPS797xx family of low-dropout (LDO) voltage regulators offers the benefits of low-dropout voltage and ultralow-power operation. The device is stable with any capacitor (>0.47 µF). Therefore, implementations of this device require very little board space due to the miniaturized packaging and potentially small output capacitor. In addition, the family includes an integrated open drain active-high power good (PG) output. Intended for use in microcontroller based, battery-powered applications, the TPS797xx family's low dropout and ultralow-powered operation results in a significant increase in system battery operating life. The small packaging minimizes consumption of board space. The device is enabled when the applied voltage exceeds the minimum input voltage. The usual PNP pass transistor has been replaced by a PMOS pass

¶ Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. NOTE 1: All voltage values are with respect to network ground terminal.

NOTES: 2. To calculate the minimum input voltage for your maximum output current, use the following formula: VI(min) = VO(max) + VDO (max load) 3. Continuous output current is limited by internal protection circuitry, but it is not recommended that the device operate under conditions beyond those specified in this table for extended periods of time. 4. The minimum IN operating voltage is 1.8 V or VO (typ) + 1 V, whichever is greater. The maximum IN voltage is 5.5 V. There is no minimum output current requirement and the maximum output current is 10 mA. 5. IN voltage equals VO(typ) ­100 mV; The TPS79730 input voltage is set to 2.9 V and the TPS79733 input voltage is set to 3.2 V. The TPS79718 dropout voltage is limited by input voltage range limitations.
