MIC5212

Dual 500mA LDO Regulator

Final

General Description

Features

The MIC5212 is a dual linear voltage regulator with very-low

dropout voltage (typically 10mV at light loads and 350mV at

500mA), very-low ground current (225µA at 10mA output),

and better than 1% initial accuracy.

• Fused lead frame SOIC-8

• Up to 500mA per regulator output

• Low quiescent current

• Low dropout voltage

• Tight load and line regulation

• Low temperature coefficient

• Current and thermal limiting

• Reversed input polarity protection

Both regulator outputs can supply up to 500mA at the same

time as long as each regulator’s maximum junction tempera-

ture is not exceeded.

Key features include current limiting, overtemperature shut-

down, and protection against reversed battery.

Applications

The MIC5212 is available in a fixed 3.3V/2.5V output voltage

configuration. Othervoltagesareavailable;contactMicrelfor

details.

• Hard disk drives

• CD R/W

• Bar code scanners

• SMPS post regulator/DC-to-DC modules

• High-efficiency linear power supplies
