MIC2214 Micrel, Inc. MIC2214
Portable Power Management IC General Description Features The MIC2214 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 and includes a power-on reset function.
The open-drain output is capable of sinking 150mA for LED
backlighting applications.
Ideal for battery operated applications, the MIC2214 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 MIC2214 can be
put into a zero-off-mode current state, drawing no current
when disabled.
The MIC2214 is a ВµCap design, operating with very small
ceramic output capacitors for stability, reducing required
board space and component cost.
The MIC2214 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 MLF™ 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 1 Open-drain driver 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 3mm × 3mm MLF™-10 package Applications Cellular/PCS phones Wireless modems PDAs Typical Application 100kΩ
