So I wired a 7812 and a 7805 in series with the input to the 7805 connected to the output of the 7812. I was expecting 12V and 5V respectively but I got instead 11V and 5V. what happened to that extra volt?
I supplied the 7812 with 15V (even brought it up to 20V same issue). I'm aware of the voltage drop across linear regulators but I thought that since there was a significant difference in voltage I would be safe.
I quickly solved the problem by connecting the inputs to both regulators in parallel, I was just curious if anyone knew why this was?
