Description

The MIC2211 is a dual Cap, 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 48A 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 Cap 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^TM leadless package.
