Device Overview

Summary

The MIC5357 is a tiny dual Ultra Low Dropout (ULDO) linear regulator ideally suited for portable electronics due to its low output noise. The MIC5357 provides two independently controlled high performance 500mA LDOs with typical dropout voltage of 130mV at rated load. In addition, the MIC5357 provides a bypass pin to reduce the output noise.

The MIC5357 is designed to be stable with small ceramic output capacitors, thereby reducing required board space and component cost. The combination of extremely low dropout voltage, low output noise, and exceptional thermal package characteristics makes it ideal for powering RF and noise-sensitive circuitry, cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players, and webcam applications.

The MIC5357 ULDO is available in fixed output voltages in the small 8-pin ePad MSOP package.
