MIC5216-5.0YMM Microchip

MIC5216 500mA-Peak Output LDO Regulator General Description Features The MIC5216 is an efficient linear voltage regulator with Error Flag indicates undervoltage fault high peak output current capability, very low dropout Guaranteed 500mA-peak output over the full operating voltage, and better than 1% output voltage accuracy. temperature range Dropout is typically 10mV at light loads and less than Low 500mV maximum dropout voltage at full load 500mV at full load. Extremely tight load and line regulation The MIC5216 is designed to provide a peak output current Tiny SOT-23-5 and MM8 power MSOP-8 package for startup conditions where higher inrush current is Low-noise output demanded. It features a 500mA peak output rating. Low temperature coefficient Continuous output current is limited only by package and layout. Current and thermal limiting Reversed input polarity protection The MIC5216 has an internal undervoltage monitor with a flag output. It also can be enabled or shutdown by a CMOS/TTL-compatible enable/shutdown control CMOS or TTL compatible signal. When disabled, power Near-zero shutdown current consumption drops nearly to zero. Dropout ground current is minimized to help prolong battery life. Other key features Applications include reversed-battery protection, current limiting, overtemperature shutdown, and low noise performance. Laptop, notebook, and palmtop computers The MIC5216 is available in fixed output voltages in Cellular telephones and battery-powered equipment space-saving SOT-23-5 and MM8 8-pin power MSOP Consumer and personal electronics packages. For higher power requirements see the PC Card V and V regulation and switching CC PP MIC5209 or MIC5237.
