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 reversed- battery protection, current limiting, overtemperature shut- down, and low noise performance.

The MIC5216 is available in fixed output voltages in space- saving SOT-23-5 and MM8(TM) 8-lead power MSOP pack- ages.  For higher power requirements see the MIC5209 or MIC5237.
