TPS70402PWPRG4

Product Summary

The TPS70402PWPRG4 is a voltage regulator 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 TPS70402PWPRG4 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. The TPS70402PWPRG4 voltage regulator offers very low dropout voltage and dual outputs with power up sequence control, which is designed primarily for DSP applications. The TPS70402PWPRG4 has low noise output performance without using any added filter bypass capacitors and is designed to have a fast transient response and be stable with 47 μF low ESR capacitors.
