General Description

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.

Ideal for battery operated applications, the MIC2211 offers 1%

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

and extremely low ground current (only 48µA total). 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.

The MIC2211 is available in ﬁxed output voltages in the

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