Description

General part information

TPS70351 Series

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.

The TPS703xx family of voltage regulators offers very low dropout voltage and dual outputs with power up sequence control, designed primarily for DSP applications. These devices have low noise output performance without using any added filter bypass capacitors, and are designed to have a fast transient response and be stable with 47 µF low ESR capacitors.

These devices have fixed 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 adjustable voltage options. Regulator 1 can support up to 1 A, and regulator 2 can support up to 2 A. Separate voltage inputs allow the designer to configure the source power.
