The MIC5216BMM 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 MIC5216BMM is designed to provide a peak output current for startup conditions where higher in-rush current is demanded. It features a 500mA peak output rating. Continuous output current is limited only by package and layout.
The MIC5216BMM 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, over-temperature shutdown, and low noise performance.
The MIC5216BMM is available in fixed output voltages in space-saving SOT-23-5 and MM8® 8-pin power MSOP packages. For higher power requirements, see the MIC5209 or MIC5237.
