Micrel Inc. • 2180 Fortune Drive • San Jose, CA 95131 • USA • tel +1 (408) 944-0800 • fax + 1 (408) 474-1000 • http://www.micrel.com April 2006 M9999-042406 (408) 955-1690 General Description 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. 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 can be found on Micrel’s web site at www.micrel.com.
