General Description
The MIC5219 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 MIC5219 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 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, overtemperature shutdown,
and low noise performance with an ultra-low-noise option.
The MIC5219 is available in adjustable or fixed output volt -
ages 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. For higher power requirements see the
MIC5209 or MIC5237.
