LM317 output incorrect #699

Closed tekinozbek closed 2 years ago

I'm getting 1.7V output for a classic LM317 5V setup:

Additionally, sometimes the component will output values < 1.25V (for V(in) > 1.25V of course):

That looks righter :)

I guess just a bug with the built-in module.

pfalstad commented 2 years ago

ok I fixed this but you will have to re-create the LM317. the old one won't show up. I assume this isn't a big deal since obviously no one was using the LM317.

Thank you, verified. Much appreciated! :)
