I have the following circuit. I know a p channel MOSFET can do it (to switch the peripheral on/off from ESP32 logic) but I am looking for a variation. Looking for least amount of parts, smallest in size for surface mount assembly that can go in the middle - I would like to have +3.3v at source so th…

Yes, you need your GPIO pin to drive an N-channel mosfet (or NPN transistor), which in turn drives the gate of the main P-channel mosfet. Below is an example. [Switching High Voltage with Arduino]

Need help with switch circuit - all 3.3v - mofset(s)?
