I am using an Adafruit Trinket Pro 3.3V and I need to use one of it's digital outputs to apply 5V power to another board that only draws 30ma. It needs to be positive logic so that a high on the trinket pin applies 5V to the second board. The 5V source I have is regulated and filtered. I would like the switch circuit to use a few components as possible. An IC would be okay if it can work with 5V.
What would a switch like that look like?
