asmo said:Hi I'm building a circuit bent instrument with several circuits in it.
I want to run them all off one power supply rather than several
different battery packs, I want to run 4 3v dc circuits from a 12v dc
power supply, can anyone point me to a schematic?
Might be easy, might not.
How much current do each of the 3 volt loads need?
Do any signals communicate between these 4 circuits?
This is a way of asking if these circuits need to be
isolated from each other or may share a common negative or
positive supply rail.
