描述 Description

The MIC2214 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 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 MIC2214 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 MIC2214 can be put into a zero off-mode current state, drawing no current when disabled.The MIC2214 is a μCap design, operating with very small ceramic output capacitors for stability, reducing required board space and component cost.
