Device Overview

Summary

The MIC5350 is a tiny dual Ultra Low Dropout (ULDO) linear regulator ideally suited for portable electronics due to its low output noise. The MIC5350 integrates two high-performance; 300mA (VOUT1) and 500mA (VOUT2) ULDOs, which provides exceptional thermal characteristics.

The MIC5350 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 MIC5350 ULDO is available in fixed output voltages in which occupies less than half the board area of a single SOT23-6 package.
