MIC2214
Portable Power Management IC
General Description
The MIC2214 is a dual
μ
Cap, low dropout regulator with an
open-drain driver and power-on reset circuit. The first regu-
lator is capable of sourcing 150mA, while the second regula-
tor 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 48
μ
A 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
μ
Cap 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.
