MIC5219YM Datasheet

Low Dropout Regulators - LDO


The MIC5219YM is an efficient linear voltage regulator with high peak output current capability, very-low-dropout voltage, and better than 1% output voltage accuracy. Dropout is typically 10mV at light loads and less than 500mV at full load.The MIC5219YM is designed to provide a peak output current for start-up conditions where higher inrush current is demanded. It features a 500mA peak output rating. Continuous output current is limited only by package and layout. MIC5219YM Features • Low 500mV maximum dropout voltage at full load• Extremely tight load and line regulation• Tiny SOT-23-5 and MM8™ power MSOP-8 package• Ultra-low-noise output• Low temperature coefficient• Current and thermal limiting• Reversed-battery protection• CMOS/TTL-compatible enable/shutdown control• Near-zero shutdown current MIC5219YM Applications • Laptop, notebook, and palmtop computers• Cellular telephones and battery-powered equipment• Consumer and personal electronics• PC Card VCC and VPP regulation and switching• SMPS post-regulator/DC-to-DC modules• High-efficiency linear power supplies
