Description

The MIC2210 is a dual Cap 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 and includes a power-on reset function.

The open-drain output is capable of sinking 150mA for LED backlighting applications. Ideal for battery operated applications, the MIC2210 offers 1% accuracy, extremely low dropout voltage (80mV @ 100mA), and extremely low ground current, only 48A total. Equipped with a TTL logic compatible enable pin*, the MIC2210 can be put into a zero-off-mode current state, drawing no current when disabled.

The MIC2210 is a Cap design, operating with very small ceramic output capacitors for stability, reducing required
board space and component cost.

The MIC2210 is available in fixed output voltages in the 10-pin 3mm ] 3mm MLF leadless package and is also
available with adjustable output voltages in the 4mm ] 4mm 16-pin MLF package.
