MIC5254

Dual 150mA µCap LDO with Error Flag Outputs

General Description

Features

The MIC5254 is an efficient, precise, dual CMOS voltage

regulator. It offers better than 1% initial accuracy, extremely

low dropout voltage (typically 135mV at 150mA) and low

ground current (typically 90µA) over load. The MIC5254

features two independent LDOs with error flags that indicate

an output fault condition such as overcurrent, thermal shut-

down and dropout.

• Input voltage range: 2.7V to 6.0V

• Dual, independent 150mA LDOs

• Error flags indicate fault condition

• Stable with ceramic output capacitor

• Ultra-low dropout: 135mV @ 150mA

• High output accuracy:

1.0% initial accuracy

2.0% over temperature

Designed specifically for handheld and battery-powered de-

vices, the MIC5254 provides a TTL-logic-compatible enable

pin.Whendisabled,powerconsumptiondropsnearlytozero.

• Low quiescent current: 90µA each LDO

• Tight load and line regulation

• Thermal shutdown and current limit protection

• “Zero” off-mode current

• TTL logic-controlled enable input

• MSOP-10 package

The MIC5254 also works with low-ESR ceramic capacitors,

reducing the amount of board space necessary for power

applications, critical in handheld wireless devices.

Key features include current limit, thermal shutdown, faster

transient response, and an active clamp to speed up device

turnoff. The MIC5254 is available in the MSOP-10 package

and is rated over a –40°C to +125°C junction temperature

range.

Applications

• Cellular phones and pagers

• Cellular accessories

• Battery-powered equipment

• Laptop, notebook, and palmtop computers

• Consumer/personal electronics
