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.
