I suppose so, but the voltage is enough to trigger the PIC program
     mode, and it works, so I don't really need to worry about that. One
     could probably use some sort of power rectifier, or a resistor if it
     provides the voltage drop.

   Are'nt you then limiting the current capability of the reg?
