The MIC5330-SRYML 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 MIC5330-SRYML 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 dropout 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.
