The MIC5310 is a tiny Dual Ultra Low-Dropout (ULDO) linear regulator ideally suited for portable electronics due to its high power supply ripple rejection (PSRR) and ultra low output noise.

The MIC5310 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 RF/noise-sensitive circuitry, cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players and webcam applications
