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.

... AC performance. A 1µF capacitor or greater located close to the IC is recommended. Bypass Capacitor The internal reference voltage of the MIC2211 can be bypassed with a capacitor to ground to reduce output noise and increase power supply rejection (PSRR). A quick-start feature allows for quick turn-on of the output voltage regardless of the size of the capacitor. The recommended nominal bypass capacitor is 0.01µ ...
