MIC2219  
Dynamically Adjustable Dual µCap LDO  
General Description  
Features  
The MIC2219 is a dual µCap low dropout regulator. The first  
regulator is capable of sourcing 150mA, while the second  
regulator can source up to 300mA.  
• 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  
• Feedback pins externally accessible  
• Low dropout voltage of 80mV @ 100mA  
Ultra-low quiescent current of 48µA total (24µA/LDO)  
• High output accuracy:  
Ideal for battery operated applications, the MIC2219 offers  
1% accuracy, extremely low dropout voltage (80mV @  
100mA), and extremely low ground current, only 48µA total.  
EquippedwithTTLlogiccompatibleenablepins,theMIC2219  
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 additional feature incorporated in the MIC2219 is bring-  
ing out the feedback nodes to two external pins, allowing for  
dynamic adjustment of the LDO output voltages.  
+1.0% initial accuracy  
+2.0% over temperature  
• Thermal shutdown protection  
• Current limit protection  
Tiny 10-pin 3mm × 3mm MLF™ package  
The MIC2219 is a µCap design, operating with very small  
ceramic output capacitors for stability, reducing required  
board space and component cost.  
Applications  
• Cellular phones  
• Wireless modems  
• PDAs  
The MIC2219 is available in fixed output voltages in the  
10-pin 3mm × 3mm MLF™ leadless package.  
• LEDs
