General 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.

The MIC2214 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.
