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 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pass transistor has been replaced by a PMOS pass
element. Because the PMOS pass element behaves as
a low-value resistor, the dropout voltage is 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,
and 3.3-V fixed options.

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.
