MIC2210  
Dual µCap LDO with Open-Drain Driver  
REV. 11/04  
General Description  
Features  
The MIC2210 is a dual µCap low dropout regulator with an  
open-draindriverandpower-onresetcircuit.Therstregulator  
iscapableofsourcing150mA,whilethesecondregulatorcan  
source up to 300mAand includes a power-on reset function.  
The open-drain output is capable of sinking 150mA for LED  
backlighting applications.  
• 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  
• 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  
Idealforbatteryoperatedapplications,theMIC2210offers1%  
accuracy, extremely low dropout voltage (80mV @ 100mA),  
and extremely low ground current, only 48µAtotal. Equipped  
with a TTL logic compatible enable pin*, the MIC2210 can  
be put into a zero-off-mode current state, drawing no current  
when disabled.  
The MIC2210 is a µCap design, operating with very small  
ceramic output capacitors for stability, reducing required  
board space and component cost.  
Applications  
The MIC2210 is available in fixed output voltages in the  
10-pin 3mm × 3mm MLF™ leadless package and is also  
available with adjustable output voltages in the 4mm × 4mm  
16-pin MLF™ package.  
• Cellular/PCS phones  
• Wireless modems  
• PDAs  
* For each output.
