MIC2213 Micrel, Inc. MIC2213
Sequenced Portable Power Management IC General Description Features The MIC2213 is a dual ВµCap low dropout regulator with an
open-drain driver and power-on reset circuit. The п¬Ѓrst regulator is capable of sourcing 150mA, while the second regulator
can source up to 300mA. A power-on reset function monitors
both outputs, indicating a fault on either output 1 or output 2.
The open-drain output is capable of sinking 150mA for LED
backlighting applications.
The MIC2213 adds the additional feature of sequencing
between the outputs, with the output of regulator 1 having to
settle before the output of regulator 2 can begin to turn-on.
Ideal for battery operated applications, the MIC2213 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 MIC2213 can be
put into a zero-off-mode current state, drawing no current
when disabled.
The MIC2213 is a ВµCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2213 is available in п¬Ѓxed output voltages in the
10-pin 3mm Г— 3mm MLFв„ў leadless package and is also
available with adjustable output voltages in the 4mm Г— 4mm
16-pin MLFв„ў package. 2 LDO outputs Output 1 -150mA output current Output 2 -300mA output current 1 Open-drain driver Power-on reset function with adjustable delay time Sequencing between outputs 1 and 2 Input voltage range: 2.25V to 5.5V Stable with ceramic output capacitor Low dropout voltage of 80mV @ 100mA Ultra-low quiescent current of 48ВµA High output accuracy: +1.0% initial accuracy +2.0% over temperature Thermal Shutdown Protection Current Limit Protection Tiny 3mm Г— 3mm MLFв„ў-10 package Applications Cellular/PCS phones Wireless modems PDAs Typical Application 100kΩ …
