MIC5320-NNYML Datasheet PDF - Micrel

General Description
The MIC5320 is a tiny Dual Ultra Low-Dropout (ULDO™) linear regulator ideally suited for portable electronics. It is ideal for general purpose/ digital applications which require high power supply ripple rejection (PSRR) >65dB, eliminating the need for a bypass capacitor and providing two enable pins for maximum flexibility. The MIC5320 integrates two highperformance; 150mA ULDOs into a tiny 6-pin 1.6mm x 1.6mm leadless MLF® package, which provides exceptional thermal package characteristics
