DESCRIPTION
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.
