Micrel's MIC5350 is a tiny, dual, ultra low-dropout (ULDO™) linear regulator, which is ideally suited for portable electronics due to its low output noise. The MIC5350 integrates high-performance 300 mA (V OUT1) and 500 mA (V OUT2) ULDOs™ into a tiny 2 mm x 2 mm leadless Thin MLF® package, which provides exceptional thermal characteristics.
The MIC5350 is designed to be stable with small ceramic output capacitors, thereby reducing required board space and component cost. The combination of extremely low-drop-out voltage, low output noise, and exceptional thermal package characteristics makes it ideal for powering RF and noise-sensitive circuitry, cellular phone camera modules, imaging sensors for digital still cameras, PDAs, MP3 players and webcam applications.
