DESCRIPTION/ORDERING INFORMATION
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 mF). 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pass transistor has been replaced by a PMOS pass element.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,
125 mV (typ) at 10 mA of load current and is directly
proportional to the load current. The quiescent current
is ultralow (1.2 mA typ) 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.
