The TPS773xx and TPS774xx are low-dropout  
regulators with integrated power-on reset and  
power good (PG) function respectively. These  
devicesarecapableofsupplying250mAofoutput  
current with a dropout of 200 mV (TPS77333,  
TPS77433). 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 TPS773xx or TPS774xx is offered in 1.8-V, 2.7-V, 2.8-V and 3.3-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 TPS773xx and TPS774xx families are available in 8-pin MSOP (DGK)  
packages.
