MIC2211

Dual µCap LDO in 3mm × 3mm MLF™

General Description

Features

The MIC2211 is a dual µCap low dropout regulator. The ﬁrst

regulator is capable of sourcing 150mA, while the second

regulator can source up to 300mA.

• 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

• Low dropout voltage of 80mV @ 100mA

• Ultra-low quiescent current of 48µA total (24µA/LDO)

• 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,theMIC2211offers1%

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

andextremelylowgroundcurrent(only48µAtotal). Equipped

with TTL logic compatible enable pins, the MIC2211 can be

put into a zero-off-mode current state, drawing no current

when disabled. Separate enable pins allow individual control

of each output voltage.

The MIC2211 is a µCap design, operating with very small

ceramic output capacitors for stability, reducing required

board space and component cost.

Applications

• Cellular phones

• Wireless modems

• PDAs

The MIC2211 is available in ﬁxed output voltages in the

10-pin 3mm × 3mm MLF™ leadless package.
