General Description

The MIC5326 is a low quiescent current, low dropout regulator designed for optimal performance in a small space. The MIC5326 is capable of sourcing 150mA 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.
