Re: gEDA-user: wrong pinout lm7912 symbol

["Bert Timmerman" <bert.timmerman@xxxxxxxxx>]

Hi all,

I think Gene is right.

In the git.gpleda repo "lm7912-1.sym" gives:

Pin #1 -> IN
Pin #2 -> GND
Pin #3 -> OUT

Which is just like any TO220 LM78xx would be :-(

Kind regards,

Bert Timmerman.

That pinout is correct for a LM7912 TO-220.
You are thinking of the LM7812 positive voltage regulator.
