MIC2210

Dual µCap LDO with Open-Drain Driver

General Description

Features

The MIC2210 is a dual µCap, low dropout regulator with

an open-drain driver and power-on reset circuit. The first

regulator is capable of sourcing 150mA, while the second

regulator can source up to 300mA and includes a power-

on reset function. The open-drain output is capable of

sinking 150mA for LED backlighting applications.

• Input voltage range: 2.25V to 5.5V

• Stable with ceramic output capacitor

• 2 LDO outputs

–

Output 1 - 150mA output current

Output 2 - 300mA output current

• 1 Open-drain driver

Ideal for battery operated applications, the MIC2210 offers

1% accuracy, extremely low dropout voltage (80mV @

100mA), and extremely low ground current, only 48µA

total. Equipped with a TTL logic compatible enable pin*,

the MIC2210 can be put into a zero-off-mode current state,

drawing no current when disabled.

• Low dropout voltage of 80mV @ 100mA

• Ultra-low quiescent current of 48µA

• High output accuracy:

–

+1.0% initial accuracy

+2.0% over temperature

The MIC2210 is a µCap design, operating with very small

ceramic output capacitors for stability, reducing required

board space and component cost.

• Thermal shutdown protection

• Current limit protection

• Tiny 10-pin 3mm × 3mm MLF^®package

The MIC2210 is available in fixed output voltages in the

10-pin 3mm × 3mm MLF^®leadless package.

Data sheets and support documentation can be found on

Micrel’s web site at www.micrel.com.

Applications

• Cellular/PCS phones

• Wireless modems

• PDAs
