$Features & Applications

The MIC29302WU TR is a high current, high accuracy and low-dropout voltage regulator based on Micrel's proprietary Super Beta PNP process with a PNP pass element.

This regulator features a very low ground current and typical dropout voltage from 350 mV to 425 mV, Ideally used where tiny dropout voltage and ground current values are more important.
