If you don't want it adjustable, use
a 7812 as if it was an LM317 (gnd leg is the adj leg)
That's a bit ambiguous, the pinouts in the TO220 variants go thus:
78XX = output / gnd / input
LM317 = input / output / adj
The tab on the 78XX is Gnd while on the LM317T it is the output.
Data sheets are on the web from NatSemi and others for verification.
