DESCRIPTION

The TPS70175 is designed to provide a complete

power management solution for the TMS320™ DSP

family, processor power, ASIC, FPGA, and digital

applications where dual output voltage regulators are required. Easy programmability of the sequencing

function makes the TPS70175 ideal for any TMS320

DSP applications with power sequencing

requirements. Differentiated features, such as

accuracy, fast transient response, SVS supervisory circuit, manual reset inputs, and an enable function,

provide a complete system solution.

The TPS70175 voltage regulator offers low dropout

voltage and dual outputs with power-up sequence

control, which is designed primarily for DSP

applications. These devices have extremely low noise

output performance without using any added filter

bypass capacitors and are designed to have a fast

transient response and be stable with 10-mF low ESR

capacitors.

This device has a fixed 5 V/2.5 V voltage option.

Regulator 1 can support up to 500 mA and regulator

2 can support up to 250 mA. Separate voltage inputs

allow the designer to configure the source power.
