FEATURES  
DESCRIPTION  
23  
•
Dual Output Voltages for Split-Supply  
The TPS704xx family of devices consists of  
dual-output, low-dropout voltage regulators with  
integrated SVS (RESET, POR, or power on reset)  
and power good (PG) functions. These devices are  
capable of supplying 1 A and 2 A by regulator 1 and  
regulator 2 respectively. Quiescent current is typically  
185 mA 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 TPS703xx for Sequenced Outputs)  
•
Output Current Range of 1 A on Regulator 1  
and 2 A on Regulator 2  
•
•
Fast Transient Response  
Voltage Options: 3.3-V/2.5-V, 3.3-V/1.8-V,  
3.3-V/1.5-V, 3.3-V/1.2-V, and Dual Adjustable  
Outputs
