MIC2211 Micrel, Inc. MIC2211
Dual ВµCap LDO in 3mm Г— 3mm MLFв„ў General Description Features The MIC2211 is a dual ВµCap low dropout regulator. The п¬Ѓrst
regulator is capable of sourcing 150mA, while the second
regulator can source up to 300mA.
Ideal for battery operated applications, the MIC2211 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 MIC2211 can be
put into a zero-off-mode current state, drawing no current
when disabled. Separate enable pins allow individual control
of each output voltage.
The MIC2211 is a ВµCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2211 is available in п¬Ѓxed output voltages in the
10-pin 3mm Г— 3mm MLFв„ў 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 Low dropout voltage of 80mV @ 100mA Ultra-low quiescent current of 48ВµA total (24ВµA/LDO) High output accuracy: +1.0% initial accuracy +2.0% over temperature Thermal shutdown protection Current limit protection Tiny 10-pin 3mm Г— 3mm MLFв„ў package Applications Cellular phones Wireless modems PDAs Typical Application
