There's a TO92 package out there, too.
Is the TO92 package for LM79xx or for an
If someone are about to fix these regulators in the distro, perhaps it
vas an idea to drop the net=GND:2 for the 78xx 79xx.
Reason: One are free to put the gnd pin on top of a couple of 1N4148's
to raise the output voltage.

There are also LM78Lxx that comes in TO92 (most popular), TO39, SO8, SOT89

thanks for the tip - I actually needed a small package version of the
5volt version but didn't locate one!

That pinout is correct for a LM7912 TO-220.
You are thinking of the LM7812 positive voltage regulator.
Here's the correct pinout for both positive and negative regulators,
with link to data sheets:
Pinout for LM7812
1. Input
2. Ground
3. Output

Wait till one of the developers correct it and puts it to the repo ;-).

Only for the TO92, right? The TO220 doesn't match. I have different
symbols for the two for 7805.

In gschem version 20070526, the symbol lm7912 has incorrect pinout.
Assuming it's TO-220, pinout should be:
1. GND
2. INPUT
3. OUTPUT
but the symbol in library has pin2 1 and 2 reversed.
That pinout is correct for a LM7912 TO-220.
