FEATURES  
DESCRIPTION  
23  
Dual Output Voltages for Split-Supply  
The TPS702xx is a low dropout voltage regulator with  
integrated SVS (RESET, POR, or power on reset)  
and power good (PG) functions. These devices are  
capable of supplying 500mA and 250mA by regulator  
1 and regulator 2 respectively. Quiescent current is  
typically 190μA at full load. Differentiated features,  
such as accuracy, fast transient response, SVS  
supervisory circuit (power on reset), manual reset  
input, and independent enable functions provide a  
complete system solution.  
Applications  
Independent Enable Functions (See Part  
Number TPS701xx for Sequenced Outputs)  
Output Current Range of 500mA on Regulator  
1 and 250mA on Regulator 2  
Fast Transient Response  
Voltage Options: 3.3V/2.5V, 3.3V/1.8V,  
3.3V/1.5V, 3.3V/1.2V, and Dual Adjustable  
Outputs
