E emc2 New Member Feb 10, 2011 #1 I'm looking into building my own power supply and have come accross a few circuits that use either the LM317 or LM317T. I cant seem to figure out if there is a difference between these two voltage regulators or not. Are they interchangeable?

DemonicSandwich Member Feb 10, 2011 #2 There is no functional difference as they are one in the same. The T at the end just indicates that it's in a TO-220 package. They usually tag on extra things after the part name to reference things like package, temp range, etc.
