General Description

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 integrates two high-performance; 150mA ULDOs into a very compact 1.6mm x 1.6mm leadless Thin MLF® package with exceptional thermal package characteristics.
