Bummer on the footprint Andy. That's burned many a pcb designer, myself included....repeatedly.
So at least you know you have company and that it will happen again in the future.
Sometimes, you can just flip your part upside down, or upside down and rotate 120 degrees to at least get your prototype going. This works much better with sot23's than it does with sot-223s.
I finally made a rule at my company....ALL three terminal packages in the master pcb library are numbered 1,2,3 left to right. PEROID! Then you make the schematic part match the datasheet in *function* & disregard the pin #s in the datasheet, if they happen to be 1,3,2 which many are. What we found is that many times we had the schematic proper but the wrong flavor of footprint was being pulled from the pcb library as we had multiples pinouts represented. During design review it's easier to see the schematic error than it is to notice the footprint. We also made it mandatory that the pin *numbers* show up on the schematic & aren't hidden to make it cleaner. No E,C,B instead of pin numbers or G,S,D, ect. You can have those as additional information, but the numbers 1,2,3 better be on there. Couple that with the fact that you *know* the footprint is 1,2,3 L-R and it's easy to review with just the schematic and datasheet in front of you.
After a while all the parts in your library have been tested by fire, so when you grab one you know its proven which also helps....now lets hope I don't blow a footprint on my next layout and have to own up to it here. lol
Great job on the jaguar, BTW. I haven't looked at it in great detail yet, but from what I saw it has been well thought out and executed.
