MIC5219

500mA-Peak Output LDO Regulator

General Description

Features

The MIC5219 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.

• 500mA output current capability

TheMIC5219isdesignedtoprovideapeakoutputcurrentfor

start-upconditionswherehigherinrushcurrentisdemanded.

It features a 500mA peak output rating. Continuous output

current is limited only by package and layout.

MSOP-8 package - 500mA continuous

• Low 500mV maximum dropout voltage at full load

• Extremely tight load and line regulation

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

• Ultra-low-noise output

• Low temperature coefﬁcient

• Current and thermal limiting

• Reversed-battery protection

• CMOS/TTL-compatible enable/shutdown control

• Near-zero shutdown current

The MIC5219 can be enabled or shut down by a CMOS or

TTL compatible signal. When disabled, power consumption

drops nearly to zero. Dropout ground current is minimized to

and low noise performance with an ultra-low-noise option.

The MIC5219 is available in adjustable or ﬁxed output volt-

Applications

• Laptop, notebook, and palmtop computers

• Cellular telephones and battery-powered equipment

• Consumer and personal electronics
