I accidentally designed and made up a bunch of boards which have the pinout of a 7805 in place of a 3V3 regulator. The 7805 pinout, from left to right, is IN,GND,OUT and the only 3V3 regulators I can find have a pinout of GND,OUT,IN. Is there anywhere I can order some regulators with the updated pinout?
How about UA78M33?

You can also (if only doing a few units) bend the pins around to make them work with the other pinout, assuming it's the usual old TO-220 package... (that teflon sleeve insulator that you can get is good for making this more resistant to shorts if the package is pushed around).
