Typical Applications
MIC5219
500mA-Peak Output LDO Regulator
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
startup 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 shut-
down, and low noise performance with an ultra-low-noise
option.
The MIC5219 is available in adjustable or fixed output volt-
ages in space-saving SOT-23-5 and MM8 8-lead power
MSOP packages. For higher power requirements see the
MIC5209 or MIC5237.
