I needed to build a delay circuit so I'm following this guide:

Using this circuit, I get a delay of about 5 seconds before the LED turns on.
The only big difference is the output of the 555 is going into the gate of a [IRFZ44N MOSFET](https://www.infineon.com/dgdl/irfz44n.pdf?fileId=5546d462533600a40153563b3575220b) as I needed more power. 

However, with 5V input voltage, I can only get 3V across the drain and source.
How could I improve this circuit to give me more efficiency, closer to my 5V?

Also, I added a 330 Ohm resistor between the power and 555 to limit draw from the 555, but I don't think that does much, as it's 3V either way.
