MIC2214
Portable Power Management IC
General Description
The MIC2214 is a dual µCap, 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 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.

Exceeding maximum rating may damage the device.
The device is not guaranteed to work outside its operating rating.
The maximum allowable power dissipation of any TA (ambient temperature) is (PD(max) = TJ(max) – TA) / θJA. Exceeding the maximum
allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown.
Specification for packaged product only.
Minimum input for line regulation test is set to VOUT + 1V relative to the highest output voltage.
Dropout voltage is defined as the input-to-output differential at which the output voltage drops 2% below its nominal value measured at 1V
differential. For outputs below 2.25V, dropout voltage is the input-to-output voltage differential with the minimum input voltage 2.25V. Minimum
input operating voltage is 2.25V.
