Device Overview

Summary

The MIC5327 is a low quiescent current, low dropout regulator designed for optimal performance in a small space. The MIC5327 is capable of sourcing 300mA of output current while only consuming 24µA of operating current. This high performance LDO offers low dropout, fast transient response, good PSRR, and low output voltage noise.

The MIC5327 is an ideal solution for battery-operated applications due to ultra-low quiescent current and an extremely low dropout voltage of 180mV at 300mA. Equipped with a TTL logic-compatible enable pin, the MIC5327 can be put into a zero off-mode current state, drawing virtually no current when disabled.

MIC5327 also features thermal shutdown and current limit protection.
