MIC5357 High Performance, Low Noise Dual 500mA ULDO™ General Description Features The MIC5357 is a tiny Dual Ultra Low Dropout (ULDO™) • 2.6V to 5.5V input voltage range linear regulator ideally suited for portable electronics due • Ultra low dropout voltage: 130mV @ 500mA to its low output noise. The MIC5357 provides two • Ultra low output noise: 51µVRMS independently controlled high performance 500mA LDOs with typical dropout voltage of 130mV at rated load. In • ±2% initial output accuracy addition, the MIC5357 provides a bypass pin to reduce the • Small 8-pin ePad MSOP package output noise. • Excellent Load/Line transient response The MIC5357 is designed to be stable with small ceramic • Fast start up time: 38µs output capacitors thereby reducing required board space • µCap stable with 2.2µF ceramic capacitors and component cost. The combination of extremely low dropout voltage, low output noise and exceptional thermal • Thermal shutdown protection package characteristics makes it ideal for powering RF • Low quiescent current: 160µA with both outputs at and noise sensitive circuitry, cellular phone camera maximum load modules, imaging sensors for digital still cameras, PDAs, • Current-limit protection MP3 players and WebCa
