MIC2212
General Description
The MIC2212 is a dual μCap low dropout regulator with
power-on reset circuit. The ?rst regulator is capable of sourcing
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 48μA 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 μCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2212 is available in ?xed output voltages in the
10-pin 3mm × 3mm MLF? leadless package.
