Device Overview

Summary

The MIC5322 is a tiny Dual Ultra Low-Dropout (ULDO) linear regulator ideally suited for those applications that require high Power Supply Rejection Ratio (PSRR). It provides a bypass pin to increase PSRR for noise sensitive portable electronics.

The MIC5322 is a µCap design which enables operation with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The combination of extremely low-dropout voltage, very high power supply rejection, very low output noise and exceptional thermal package characteristics makes it ideal for powering RF applications, cellular phones, GPS, imaging sensors for digital still cameras, PDAs, MP3 players, and other portable applications.

The MIC5322 ULDO is available in fixed-output voltages in SOT-23, and TSOP.
