Microchip Technology MIC5392
The MIC5392/3 is a tiny, dual low-dropout linear regulator ideally suited for portable electronics. It is ideal for general purpose/digital applications that require high power supply ripple rejection (PSRR) >60 dB, eliminating the need for a bypass capacitor and providing two enable pins for maximum flexibility. The MIC5392/3 integrates two high-performance 150 mA LDOs into a tiny 6-pin, 1.2 mm × 1.2 mm leadless UDFN or X2DFN package, which provides exceptional thermal package characteristics.FEATURES
