General Description

The MIC5216 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 MIC5216 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 MIC5216 has an internal undervoltage monitor with a

flag output. It also can be enabled or shutdown 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

overtemperature shutdown, and low noise performance.

The MIC5216 is available in fixed output voltages in

space-saving SOT-23-5 and MM8™ 8-pin power MSOP

packages. For higher power requirements see the

MIC5209 or MIC5237.
