The TPS771xx and TPS772xx are low-dropout  
regulators with integrated power-on reset and  
power good (PG) function respectively. These  
devicesarecapableofsupplying150mAofoutput  
current with a dropout of 115 mV (TPS77133,  
TPS77233). Quiescent current is 92 µA at full load  
dropping down to 1 µA when device is disabled.  
These devices are optimized to be stable with a  
wide range of output capacitors including lowESR  
ceramic (10 µF) or low capacitance (1 µF)  
tantalum capacitors. These devices have ex-

The TPS771xx or TPS772xx is offered in 1.5 V,  
1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5.0 V fixed-voltage versions and in an adjustable version (programmable over  
the range of 1.5 V to 5.5 V). Output voltage tolerance is 2% over line, load, and temperature ranges. The  
TPS771xx and TPS772xx families are available in 8-pin MSOP (DGK) packages.  
Because the PMOS device behaves as a low-value resistor, the dropout voltage is very low (typically 115 mV  
at an output current of 150 mA for 3.3 volt option) 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 92 µA over the full range of output current, 0 mA to 150 mA). These two key  
specifications yield a significant improvement in operating life for battery-powered systems.
