description  
I

= 150 mA  
The TPS771xx and TPS772xx are low-dropout  
regulators with integrated power-on reset and  
power good (PG) function respectively. These  
devices are capable of supplying 150 mA of output  
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 low ESR  
ceramic (10 µF) or low capacitance (1 µF)  
tantalum capacitors. These devices have  
extremely low noise output performance (55

rms  
TPS771xx and TPS772xx are designed to have  
fast transient response for larger load current  
changes.  
The TPS771xx or TPS772xx is offered in 1.5 V,1.8-V, 2.7-V, 2.8-V, 3.3-V, and 5 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.
