FEATURES  
DESCRIPTION  
The LM1086 is a series of low dropout positive  
voltage regulators with a maximum dropout of 1.5V at  
1.5A of load current. It has the same pin-out as TI's  
industry standard LM317.  
2
Available in 1.8V, 2.5V, 2.85V, 3.3V, 3.45V, 5V  
and Adjustable Versions  
Current Limiting and Thermal Protection  
Output Current 1.5A  
The LM1086 is available in an adjustable version,  
which can set the output voltage with only two  
external resistors. It is also available in six fixed  
voltages: 1.8V, 2.5V, 2.85V, 3.3V, 3.45V and 5.0V.  
The fixed versions integrate the adjust resistors.  
Line Regulation 0.015% (typical)  
Load Regulation 0.1% (typical)  
APPLICATIONS  
The LM1086 circuit includes  
bandgap reference, current limiting and thermal  
shutdown.
