LM1085  
3A Low Dropout Positive Regulators  
General Description  
Features  
n Available in 3.3V, 5.0V, 12V and Adjustable Versions  
n Current Limiting and Thermal Protection  
n Output Current  
The LM1085 is a series of low dropout positive voltage  
regulators with a maximum dropout of 1.5V at 3A of load  
current. It has the same pin-out as National Semiconductor’s  
industry standard LM317.

n Line Regulation  
n Load Regulation  
0.015% (typical)  
0.1% (typical)  
The LM1085 is available in an adjustable version, which can  
set the output voltage with only two external resistors. It is  
also available in three fixed voltages: 3.3V, 5.0V and 12.0V.  
The fixed versions integrate the adjust resistors.  
Applications  
n High Efficiency Linear Regulators  
n Battery Charger  
The LM1085 circuit includes a zener trimmed bandgap ref-  
erence, current limiting and thermal shutdown.  
n Post Regulation for Switching Supplies  
n Constant Current Regulator  
n Microprocessor Supply  
The LM1085 series is available in TO-220 and TO-263 pack-  
ages. Refer to the LM1084 for the 5A version, and the  
LM1086 for the 1.5A version.
