MIC2210

Dual µCap LDO with Open-Drain Driver

REV. 11/04

General Description

Features

The MIC2210 is a dual µCap low dropout regulator with an

open-draindriverandpower-onresetcircuit.Theﬁrstregulator

iscapableofsourcing150mA,whilethesecondregulatorcan

source up to 300mAand 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

• Low dropout voltage of 80mV @ 100mA

• Ultra-low quiescent current of 48µA

• High output accuracy:

• +1.0% initial accuracy

• +2.0% over temperature

• Thermal shutdown protection

• Current limit protection

• Tiny 10-pin 3mm × 3mm MLF™ package

Idealforbatteryoperatedapplications,theMIC2210offers1%

accuracy, extremely low dropout voltage (80mV @ 100mA),

and extremely low ground current, only 48µAtotal. 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.

The MIC2210 is a µCap design, operating with very small

ceramic output capacitors for stability, reducing required

board space and component cost.

Applications

The MIC2210 is available in ﬁxed output voltages in the

10-pin 3mm × 3mm MLF™ leadless package and is also

available with adjustable output voltages in the 4mm × 4mm

16-pin MLF™ package.

• Cellular/PCS phones

• Wireless modems

• PDAs

* For each output.
