I am trying to build my own DDL based on the LM317 circuit shown on this site. I ordered some LM317s from eBay but as I had everything but those, picked up a LM317T from RadioShack today.
I bread-board build the circuit but the output voltage read too high on a volt-meter.
With 6v applied to vin, vout reads 5.45v and adj reads 5v. no matter what resisters I bridge adj and vout with, vout stays at 5.45v. Am I doing something wrong or could this actually be a bad LM? :undecided:
Thanks.
