Description

The MIC2212 is a dual Cap, low dropout regulator with power-on reset circuit. The first regulator is capable of sourc-
ing 150mA, while the second regulator can source up to 300mA and includes a power-on reset function.

Ideal for battery operated applications, the MIC2212 offers1% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 48?A total. Equipped with TTL-logic-compatible enable pins, the MIC2212 can be put into a zero-off-mode current state, drawing no current when disabled.

The MIC2212 is a Cap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.

The MIC2212 is available in fixed output voltages in the 10-pin 3mm * 3mm MLF^TM leadless package.
