description

TPS707xx family devices are designed to provide

a complete power management solution for 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 DSP applications with power sequencing

requirement. Differentiated features, such as

accuracy, fast transient response, SVS supervi-

sory circuit (power on reset), manual reset inputs,

and enable function, provide a complete system

solution.
