FEATURES  
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

50mA Low-Dropout Regulator  
Ultralow 1.2μA Quiescent Current at 10mA  
5-Pin SC70 (DCK) Package  
with  
any  
capacitor  
(> 0.47μF).  
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 low dropout and ultralow-  
powered operation results in a significant increase in  
system battery operating life. The small packaging  
minimizes consumption of board space.  
Integrated Power Good Output  
Stable With Any Capacitor (> 0.47μF)  
Dropout Voltage Typically 105mV at 10mA  
(TPS79733)

Over-Current Limitation  
–40°C to +85°C Operating Junction  
Temperature Range  
APPLICATIONS  
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pass transistor has been replaced by a PMOS pass  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 very  
low, typically 105mV at 10mA of load current, and is  
directly proportional to the load current. The  
quiescent current is ultralow (1.2μA typically) and is  
stable over the entire range of output load current  
(0mA to 50mA). When properly configured with a pull-  
up resistor, the PG output can be used to implement  
a power-on reset or low battery indicator.
