FEATURES  
DESCRIPTION  
23  
•
Dual Output Voltages for Split-Supply  
The TPS703xx family of devices is designed to  
provide a complete power management solution for  
TI DSP, processor power, ASIC, FPGA, and digital  
applications where dual output voltage regulators are  
required. Easy programmability of the sequencing  
function makes this family ideal for any TI DSP  
application with power sequencing requirements.  
Differentiated features, such as accuracy, fast  
transient response, SVS supervisory circuit (power-on  
reset), manual reset inputs, and enable function,  
provide a complete system solution.  
Applications  
•
Independent Enable Functions (See Part  
Number TPS704xx for Independent Enabling of  
Each Output)  
•
Output Current Range of 1 A on Regulator 1  
and 2A 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
