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

devices, the MIC5254 provides a TTL-logic-compatible

enable pin. When disabled, power consumption drops

nearly to zero.

• 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

• 10-pin MSOP 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 10-pin

MSOP package and is rated over a –40°C to +125°C

junction temperature range.
