MIC2213

The MIC2213 is a dual µCap low dropout regulator with an open-drain driver and power-on reset circuit. The first regulator is capable of sourcing 150mA, while the second regulator can source up to 300mA. A power-on reset function monitors both outputs, indicating a fault on either output 1 or output 2. The open-drain output is capable of sinking 150mA for LED backlighting applications.

The MIC2213 adds the additional feature of sequencing between the outputs, with the output of regulator 1 having to settle before the output of regulator 2 can begin to turn-on.

Ideal for battery operated applications, the MIC2213 offers 1% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 48µA total. Equipped with a TTL logic compatible enable pin, the MIC2213 can be put into a zero off-mode current state, drawing no current when disabled.

The MIC2213 is a µCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.
