Device Overview

Summary

The MIC5303 is an ultra-small, ultra-low dropout CMOS regulator, ULDO™ that is ideal for today's most demanding portable applications including cellular phone RF power, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players (PMPs), and PC cameras where board space is limited. It offers extremely low dropout voltage, very low output noise, and can operate from a 2.3V to 5.5V input while delivering up to 300mA.

It offers 2% initial accuracy, low ground current (typically 85µA total), and thermal and current limit protection. The MIC5303 can also be put into a zero off-mode current state, drawing no current when disabled.
