I need to protect the 12.8v regulator from the 14.5v battery.
Do I try to just reduce the battery voltage below 21.8V with a bunch of diodes? Do I just put one diode protecting against current flow into the regulator output? Do I do both? The load operates on 6-36V, and 30w.
The reason I put several diodes in the last option is this. If both the sources are connected I would like the load to take power from the regulator instead of the battery. I thought with multiple diodes in there it would take from the regulator instead of the battery. Am I right?
Need to protect the regulator from burning. Which option is correct?
