DESCRIPTION  
The LM117/LM217/LM317 are  
monolithic  
TO-3  
D2PAK  
integrated circuit in TO-220, ISOWATT220, TO-3  
and D2PAK packages intended for use as  
positive adjustable voltage regulators.  
They are designed to supply more than 1.5A of  
load current with an output voltage adjustable  
over a 1.2 to 37V range.  
The nominal output voltage is selected by means  
of only a resistive divider, making the device  
exceptionally easy to use and eliminating the  
stocking of many fixed regulators.
