description

GND/HEATSINK

TPS703xx family of devices are designed to

IN1

OUT1

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 applications with power

sequencing requirement. 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.
