I also have to say that using common positive can be confusing when you later choose to drive the load with a different voltage. Plus P-channel MOSFETs typically have worse internal resistance. Thus use an N-channel MOSFET in the common negative. And remove the curent-limiting resistor. It's for bipolars only and shows how you don't know what you are doing. Make sure that your load isn't very demanding since 5V aren't optimal for turning on a MOSFET. | |
