MIC2212
Dual
μ
Cap LDO and Power-On Reset
General Description
The MIC2212 is a dual
μ
Cap, low dropout regulator with
power-on reset circuit. The first regulator is capable of sourc-
ing 150mA, while the second regulator can source up to
300mA and includes a power-on reset function.
Ideal for battery operated applications, the MIC2212 offers
1% accuracy, extremely low dropout voltage (80mV @
100mA), and extremely low ground current, only 48
μ
A total.
Equipped with TTL-logic-compatible enable pins, the MIC2212
can be put into a zero-off-mode current state, drawing no
current when disabled.
The MIC2212 is a
μ
Cap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2212 is available in fixed output voltages in the
10-pin 3mm
×
3mm MLF leadless package.
