FEATURES  
DESCRIPTION  
The TPS740xx is a wide bandwidth, very low-dropout,  
1.5-A voltage regulator ideal for powering  
microprocessors.

VIN: 1.2 V to 5.5 V  
VBIAS: 2.9 V to 5.5 V  
The TPS740xx uses a bias input supply to allow very  
low voltage of a main input supply. The main input  
supply operates from 1.2 V to 5.5 V and the bias  
input supply requires between 3.0 V to 5.5 V for  
proper operation. The TPS740xx offers adjustable  
output voltages down to 0.9 V.

Logic-Controlled Shutdown Option  
Thermal Shutdown and Current Limit  
Protection  
The TPS740xx requires  
capacitance. A small 2.2-μF ceramic capacitor is  
enough for its stability.

The TPS740xx is available in an 8-pin power MSOP  
package and  
a 5-pin Jr S-PAK. Its operating  
temparature range is –40°C to +125°C.
