Voltage regulator pin Enabled is equal gate of the MOSFET and is working at low voltage.
Sounds interesting but I don't understand how it works. So this regulator can act like a switch?
Using P channel MOSFET it is the same as N channel, just different connection.
Thanks that's what I was thinking! The circuit we originally talked about with the N-Channel to power the 555 worked but I set it up wrong. Drain should not have been attached to Vss+
No difference in using a p-channel fet high-side or an n-channel fet low side.
Assuming this circuit is stand-alone (not connected ot anything else).
Ah okay that makes sense. Thanks!
I'm also wondering what's the use case for a MOSFET vs NPN transistor for switching power. Does one work better for this case?
