MIC2210
Dual ВµCap LDO with Open-Drain Driver General Description Features The MIC2210 is a dual ВµCap, 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 poweron reset function. The open-drain output is capable of
sinking 150mA for LED backlighting applications.
Ideal for battery operated applications, the MIC2210 offers
1% accuracy, extremely low dropout voltage (80mV @
100mA), and extremely low ground current, only 48ВµA
total. Equipped with a TTL logic compatible enable pin*,
the MIC2210 can be put into a zero-off-mode current state,
drawing no current when disabled.
The MIC2210 is a ВµCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2210 is available in fixed output voltages in the
10-pin 3mm Г— 3mm MLFВ® leadless package.
