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.

Features

• Error Flag indicates undervoltage fault

• Guaranteed 500mA-peak output over the full operating temperature range

• Low 500mV maximum dropout voltage at full load

• Extremely tight load and line regulation

• Tiny SOT-23-5 and MM8™ power MSOP-8 package

• Low-noise output

• Low temperature coefficient

• Current and thermal limiting

• Reversed input polarity protection

• CMOS/TTL-compatible enable/shutdown control

• Near-zero shutdown current

Applications

• Laptop, notebook, and palmtop computers

• Cellular telephones and battery-powered equipment

• Consumer and personal electronics

• PC Card VCC and VPP regulation and switching

• SMPS post-regulator/dc-to-dc modules

• High-efficiency linear power supplies
