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pass transistor has been replaced by a PMOS pass  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.

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.
