MIC5307  
300mA Micropower µCap  
Baseband LDO  
General Description  
Features  
The MIC5307 is a micropower, µCap low dropout regulator  
designed for optimal performance where smaller packages  
are required. It is capable of sourcing 300mA of output  
current while only drawing 20µA of operating current. This  
high performance LDO offers fast transient response and  
good PSRR while consuming a minimum of current.  
Input voltage range: 2.4V to 5.5V  
Ultra-low IQ: Only 20µA operating current  
Stable with ceramic output capacitor  
Low dropout voltage of 120mV @ 300mA  
High output accuracy  
– ±1.0% initial accuracy  
– ±2.0% over temperature  
Ideal for battery operated applications; the MIC5307 offers  
1% initial accuracy, extremely low dropout voltage and is  
equipped with a TTL logic compatible enable pin. The  
MIC5307 can be put into a zero-off-mode current state,  
drawing no current when disabled.  
Thermal Shutdown Protection  
Current Limit Protection  
The MIC5307 is a µCap design, operating with very small  
ceramic output capacitors for stability, reducing required  
board space and component cost.  
Applications  
Digital Logic Power Supply  
Stand-by power supply  
Cellular phones  
The MIC5307 is available in fixed output voltages in the  
Thin SOT23-5 package and the 6-pin 2mm x 2mm Thin  
MLF® package.
