MIC5392

MIC5392/3 High-Performance Dual 150 mA LDO Features 2.5V to 5.5V Input Voltage Range Two 150 mA Output Current LDOs High Output Accuracy - ±2% Initial Accuracy Low Quiescent Current (32 µA per LDO) Stable with 1 µF Ceramic Output Capacitors Independent Enable Pins Low Dropout Voltage (155 mV at 150 mA) Thermal Shutdown Protection 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 module...
