So i have put together a single lm317 circut using the following schematic:
(sorry for bad pic)
**broken link removed**
I am trying to do the same, but with four 317 in paralell to accomodate the laptop power supply I am using for ac to dc. The laptop supply's output is 19.5volts and 3.5amps. The output of my 317 circut is a constant .7v. Does anyone know why this is. It is currently only breadboarded and check that all my connections were pushed in properly.
Thanks,
Mike
