MIC5393

MIC5392/3 High-Performance Dual 150mA LDO Revision 1.2 General Description The MIC5392/3 is a tiny dual low-dropout linear regulator ideally suited for portable electronics. It is ideal for general purpose/digital applications which require high-power supply ripple rejection (PSRR) >60dB, eliminating the need for a bypass capacitor and providing two enable pins for maximum flexibility. The MIC5392/3 integrates two highperformance; 150mA LDOs into a tiny 6-pin, 1.2mm x 1.2mm leadless DFN package, which provides exceptional thermal package characteristics. The MIC5392/3 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 low-drop-out voltage, high power supply rejection and exceptional thermal package characteristics makes it ideal for powering mobile phones camera modules, image sensors, PDAs, MP3 players and audio codec power applications. The MIC5392/3 is available in fixed-output voltages in the tiny 6-pin 1.2mm x 1.2mm leadless DFN package which is 2 only 1.44mm in area. Additional voltage options are available.
