More View Current Limit Protection • Internal 25Ω Output Discharge Circuit (MIC5393) • 1.2 mm × 1.2 mm X2DFN Package (H ≤ 0.4 millimeter) • 1.2 mm × 1.2 mm UDFN Package Applications • Smartphones • Tablet PCs • GPS, PMP, PDAs, and Handhelds • Audio Codec Power • Portable Electronics • 5V Systems 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 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. The MIC5392/3 is a µCap design that enables operation with very small ceramic output capacitors for stability, thereby reducing required board space and component cost. The combination of low dropout 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 1.2 mm × 1.2 mm leadless UDFN or X2DFN package, which is only 1.44 mm2 in area. Additional voltage options are available.
