Any problems with running more than one 7805-type regulator in parallel?
I'm currently running a VFD display that draws ~750mA from a 7805 regulator, I have a fairly large heatsink on it, and it still runs very hot(hot enough to burn me).This is a automotive application(average voltage drop of 8 V), where temps fluctuate quite a bit, I know once this project is enclosed and in the car, I will have heat problems.I was thinking I could increase reliability with dual 7805's, any thoughts, ideas, or suggestions? maybe swapping in a switching regulator?
