DESCRIPTION/ORDERING INFORMATION  
One Fabrication Site  
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,  
Extended Temperature Performance of  
–55°C to 125°C

Qualification Pedigree(1)  
10 mA Low-Dropout Regulator  
Ultralow 1.2 µA Quiescent Current at 10 mA  
5-Pin SC70/SOT-323 (DCK) Package  
Integrated Power Good Output  
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.  
Stable With Any Capacitor (> 0.47 µF)  
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pass transistor has been replaced by a PMOS pass  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 µA 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.  
Dropout Voltage Typically 105 mV at 10 mA  
(TPS79733)

Overcurrent Limitation  
Component qualification in accordance with JEDEC and  
industry standards to ensure reliable operation over an  
extended temperature range. This includes, but is not limited  
to, Highly Accelerated Stress Test (HAST) or biased 85/85,  
temperature cycle, autoclave or unbiased HAST,  
electromigration, bond intermetallic life, and mold compound  
life. Such qualification testing should not be viewed as  
justifying use of this component beyond specified  
performance and environmental limits.
