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 http://www.onsemi.com/PowerSolutions/product.do?id=MC7812 Pinout for LM7912 1. Ground 2. Input 3. Output http://www.onsemi.com/pub/Collateral/MC7900-D.PDF I know it's correct because my breadboard didn't power up correctly. That's when I checked the pinout on the schematic and found the mistake. gene _______________________________________________ geda-user mailing list [email protected] http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
