Features & Applications

The MIC5219YMM TR is an efficient linear voltage regulator with high peak output current apability, very-low-dropout voltage, and better than 1% output voltage accuracy. Dropout is typically 10 mV at light loads and less than 500 mV at full load.

The MIC5219 is designed to provide a peak output current for start-up conditions where higher inrush current is demanded. It features a 500 mA peak output rating. Continuous output current is limited only by package and layout.

The MIC5219 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 reversed-battery protection, current limiting, over temperature shutdown, and low noise performance with an ultra-low-noise option. The MIC5219YMM TR is available in MM8 8pin power MSOP package.
