Hi,
I'm working with a microcontroller that outputs 5V, 25mA max from each pin. I need to source 120-150mA. I'm looking at 2n7000 MOSFET for the job. Spice simulations show the output current is 50mA when Vg = 5V (microcontroller output) and about 120mA when Vg = 5.5V. Since I'll be using over 20 pins from the microcontroller, amplifying the output for each pin is impractical. Is there another cheap and reliable MOSFET that can be substituted so this will work?
Thanks
