250-mA Low Dropout Voltage Regulator  
mV at an output current of 250 mA for the TPS76650)  
and is directly proportional to the output current.  
Additionally, since the PMOS pass element is a  
voltage-driven device, the quiescent current is very  
low and independent of output loading (typically 35  
µA over the full range of output current, 0 mA to 250  
mA). These two key specifications yield a significant  
improvement in operating life for battery-powered  
systems. This LDO family also features a sleep  
mode; applying a TTL high signal to EN (enable)  
shuts down the regulator, reducing the quiescent  
current to less than 1 µA (typ).

DESCRIPTION  
The TPS766xx is offered in 1.5 V, 1.8 V, 2.5 V, 2.7 V,  
2.8 V, 3.0 V, 3.3 V and 5.0 V fixed voltage versions  
and in an adjustable version (programmable over the  
range of 1.25 V to 5.5 V). Output voltage tolerance is  
specified as a maximum of 3% over line, load, and  
temperature ranges. The TPS766xx family is  
available in an 8-pin SOIC package.  
This device is designed to have an ultralow quiescent  
current and be stable with a 4.7-µF capacitor. This  
combination provides high performance at  
reasonable cost.
