Micrel MIC5310
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 integrates two high-performance 150mA ULDOs into a tiny 2mm x 2mm leadless MLF® package, which provides exceptional thermal package characteristics. 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.GENERAL DESCRIPTION
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 MIC5310 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. For more information, contact Micrel marketing department. Data sheets and support documentation are found on the Micrel web siteFEATURES
