MIC5216
500mA-Peak Output LDO Regulator
General Description Features
The MIC5216 is an efficient linear voltage regulator with
Error Flag indicates undervoltage fault
high peak output current capability, very low dropout
Guaranteed 500mA-peak output over the full operating
voltage, and better than 1% output voltage accuracy.
temperature range
Dropout is typically 10mV at light loads and less than
Low 500mV maximum dropout voltage at full load
500mV at full load.
Extremely tight load and line regulation
The MIC5216 is designed to provide a peak output current

demanded. It features a 500mA peak output rating.
Low temperature coefficient
Continuous output current is limited only by package and
layout.
Current and thermal limiting
Reversed input polarity protection
The MIC5216 has an internal undervoltage monitor with a
flag output. It also can be enabled or shutdown by a CMOS/TTL-compatible enable/shutdown control

consumption drops nearly to zero. Dropout ground current
is minimized to help prolong battery life. Other key features
Applications
include reversed-battery protection, current limiting,
overtemperature shutdown, and low noise performance.
Laptop, notebook, and palmtop computers
The MIC5216 is available in fixed output voltages in Cellular telephones and battery-powered equipment
