Dual ВµCap LDO and Power-On Reset General Description Features The MIC2212 is a dual ВµCap low dropout regulator with
power-on reset circuit. The п¬Ѓrst 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 48ВµA 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 ВµCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2212 is available in п¬Ѓxed output voltages in the
10-pin 3mm × 3mm MLF™ leadless package. Input voltage range: 2.25V to 5.5V Stable with ceramic output capacitor 2 LDO outputs Output 1 – 150mA output current Output 2 – 300mA output current Power-on reset function with adjustable delay time Low dropout voltage of 80mV @ 100mA Ultra-low quiescent current of 48µA High output accuracy: +1.0% initial accuracy +2.0% over temperature Thermal shutdown protection Current limit protection Tiny 10-pin 3mm × 3mm MLF™ package Applications Cellular/PCS phones Wireless modems PDAs Typical Application MIC2212-xxBML Li-Ion
