Does anyone know what happens if you put a LM2940 LDO regulator (In- GND-out) in a PCB designed for a MC33269D (Gnd-out-in) ? Apparently reports say that voltage on the output rises to 7V or so; I guess the big question is whether the current is limited to a value that might leave other components (an AVR) undamaged, or whether we can assume that everything is toast...
