I have a voltage source that will be either 3.7v, 5v or 12v and would like to use a 6v 300mA rated switch to turn the power on and off by using the on/off pin on a MC33375D regulator. Would appreciate if someone could tell me if my layman's understanding is correct in the below schematic.
The 4.7k 6.8k res are to reduce the voltage to 5v if the 12v source is in use. The 10k is to make the pin set to off by default. Of course, my overall assumption is that the schottky diodes attached to each source will result in only one of them being used even if all are attached. Is this correct?
