MICROCHIP MIC5320-PKYML

The MIC5320 is a tiny Dual Ultra Low-Dropout (ULDO™) linear regulator ideally suited for portable electronics. It’s ideal for today’s most demanding ultra-thin portable applications including mobile phones, camera modules, imaging sensors for digital still and video cameras, PDAs, portable media players (PMP) and PC cameras. The MIC5320 integrates two high-performance, 150mA ULDOs into a tiny 6-pin 1.6mm x 1.6mm leadless Thin MLF package, which provides exceptional thermal package characteristics. The MIC5320 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-dropout voltage, fast transient response and exceptional thermal package characteristics makes it ideal for portable electronics. The MIC5320 ULDO™ is available in fixed-output voltages in the tiny 6-pin 1.6mm x 1.6mm leadless Thin MLF package which is only 2.56mm² in area, less than 30% the area of the SOT-23, TSOP and MLF 3x3 packages. It’s also available in the thin SOT-23-6 lead package and the standard 6-pin 1.6mm x 1.6mm leadless package. Additional voltage options are available.
