MIC38300A Datasheet Ultra-Low Noise 3A Power Module

Manufacturer: Microchip Technology

General Description

The MIC38300A is a 3A current step-down converter that provides the benefits of an LDO in respect to ease of use, fast transient performance, high PSRR, and low noise while offering the efficiency of a switching regulator.

As output voltages move lower, the output noise and transient response of a switching regulator become an increasing challenge for designers.

By combining a switcher whose output is slaved to the input of a high-performance LDO, high efficiency is achieved with a clean low noise output.
