3-Terminal Positive Adjustable Regulators  
GENERAL DESCRIPTION  
The LM317T are monolithic integrated circuits in TO220 packages.  
They are intended for use as positive adjustable voltage regulators, and designed to supply  
more than 1.5A of load current whit an output voltage adjustable over a 1.2 to 37V range.  
Compliance to RoHS.
