MICROCHIP MIC5330-OOYML-TR

The MIC5330 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 integrates two high performance 300mA ULDOs into a tiny 2mm x 2mm leadless MLF package, which provides exceptional thermal package characteristics. The MIC5330 is a ACap 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. The MIC5330 ULDO™ is available in fixed output voltages in the tiny 8 - pin 2mm x 2mm leadless MLF package which occupies less than half the board area of a single SOT - 6 package. Additional voltage options are available.
