  1. Thanks for the help. The package for the lm317 is not clear as to which side is down. I got it working and am using it for a 4-H Fair as a demonstrations. Thanks for all the help.
  2. I bought the lm317t from radio shack. It shows on the package that 2 is the out or the middle pin. As the picture goes I think with the pins pointing down looking at the thing with the heat sink part laying on the table pin 3 is on the left and then pin 2 is center and pin one is right. Here is the schematic of my power supply, only I have a 25 v 450 ma transformer. I had it working for a minute and put a meter on the output and the fuse blew. I tried again after checking it and it blew as soon as i turned it on.
  3. I tried it with this and i have a two amp fuse on one side of the input and it is blowing???
  4. Hello, i was wondering if it was possible to use a 450 ma 25 volt transformer on this lm317 power supply
