... It features a 500mA 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 ...

... The capacitor can be reduced to 0.47µF for current below 10mA, or 0.33µF for currents below 1mA. No-Load Stability The MIC5219 will remain stable and in regulation with no load (other than the internal voltage divider) unlike many other voltage regulators. This is especially important in CMOS RAM keep-alive applications ...
