L293D used to reverse motor direction 7.8 vdc

You will need to put the 7.8V onto pin 8 (VCC2) and all your switching and VCC1 have to be 5V. So you need a LM7805 voltage regulator to derive that 5V.

Hi thanks assume the lm7805 can just come off the end of the main feed ( going to vcc2pin 8) so betweem 8 and 16 or does it need dedicated feed?
thanks
