Yeah, will doOuch. I'd still try to fix the short and see if that revives it. You should probably get a better iron tip if that's what knocked them off. You should probably get one anyways, as a narrow tip will make soldering to the little things a LOT easier.
this iron seems like it's just too big. The other regulators are fine though... I'm just going to hope I can fix it. I can alway try to measure what the resistance is using the other regs and try to replace it, using normal resistors of course. I hope I can revive this one though since I have a LOT to do in order to finish the portable in time for the contest.
