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
