Use mosfet to switch on/off a microcontroller


#1

I want tos switch a 3.3v load ( 150mA peak) from a 3.3v microcontroller, what mosfet shall I use? I tried IRF540N but it provides enough current to the load only when gate voltage is 3.95v and above. I’m limited to a maximum gate voltage of 3.3v.


#2

I have controlled using BSS138BK and BUK series of NXP at 3V to 3.3V
