TPS70302PWP

Product Summary

The TPS70302PWP is a dual-output low-dropout voltage regulator with power up sequencing for split voltage dsp systems. The TPS70302PWP 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 the TPS70302PWP 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.
