MIC5303  
Single 300mA CMOS  
Ultra Small ULDO™  
General Description  
Features  
Ultra Small 1.2mm x 1.6mm Thin MLF® package  
Low Dropout Voltage: 100mV at 300mA  
Output noise 120µVrms  
The MIC5303 is an ultra small, Ultra Low Dropout CMOS  
regulator, ULDO™ that is ideal for today’s most demand-  
ing portable applications including cellular phone RF  
power, camera modules, imaging sensors for digital still  
and video cameras, PDAs, portable media players (PMP)  
and PC cameras where board space is limited. It offers  
extremely low dropout voltage, very low output noise and  
can operate from a 2.3V to 5.5V input while delivering up  
to 300mA.  
Input voltage range: 2.3V to 5.5V  
300mA guaranteed output current  
Stable with ceramic output capacitors  
Low quiescent current 85µA total  
35µs turn-on time  
It offers 2% initial accuracy, low ground current (typically  
85µA total), thermal and current limit protection. The  
MIC5303 can also be put into a zero-off-mode current  
state, drawing no current when disabled.  
High output accuracy  
– ±2% initial accuracy  
– ±3% over temperature  
Thermal shutdown and current limit protection  
The MIC5303 is available in the ultra small 4-pin 1.2mm x  
1.6mm Thin MLF® package, occupying only 1.92mm2 of  
PCB area, a 50% reduction in board area compared to  
SC-70 and 2mm x 2mm MLF® packages. It’s operating  
junction temperature range is –40°C to +125°C and is  
available in fixed output voltages in lead-free (RoHS  
compliant) Thin MLF® package.  
Applications  
Mobile Phones  
PDAs  
GPS Receivers  
Portable Media Players  
Portable Electronics  
Digital Still & Video Cameras
