Microchip | MIC5320-JGYML-TR

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 high performance; 150mA ULDOs into a tiny 6-pin 1.6mm x 1.6mm leadless Thin MLF® package, which provides exceptional thermal package characteristics.

The MIC5320 is a µCap design which enables operation with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The combination of extremely low-drop-out voltage, high power supply rejection and exceptional thermal package characteristics makes it ideal for powering cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players and WebCam applications.
