Product Summary

The MIC5219YM5 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 MIC5219YM5 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.The MIC5219YM5 can be enabled or shut down 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 with an ultra-low-noise option. The MIC5219YM5 is available in adjustable or fixed output voltages in the space-saving 6-pin (2mm × 2mm) MLF®, 6-pin (2mm × 2mm) Thin MLF® SOT－23－5 and MM8® 8－pin power MSOP packages.
