MIC5216

MIC5216 Micrel MIC5216 500mA-Peak Output LDO Regulator Preliminary Information General Description The MIC5216 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 MIC5216 is designed to provide a peak output current for startup conditions where higher inrush current is demanded. It features a 500mA peak output rating. Continuous output current is limited only by package and layout. The MIC5216 has an internal undervoltage monitor with a flag output. It also can be enabled or shutdown by a CMOS or TTL compatible signal. When disabled, power consumption drops nearly to zero. Dropout ground current is minimized to help prolong battery life. Other key features include reversedbattery protection, current limiting, overtemperature shutdown, and low noise performance. The MIC5216 is available in fixed output voltages in spacesaving SOT-23-5 and MM8™ 8-lead power MSOP packages. For higher power requirements see the MIC5209 or MIC5237.
