Microchip | MIC5330-PKYML-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; 300 mA ULDOs into a tiny 2 mm x 2 mm leadless MLF ® package, which provides exceptional thermal package characteristics.

The MIC5330 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 MIC5330 ULDO™ is available in fixed-output voltages in the tiny 8-pin 2 mm x 2 mm 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.
