7805 and grids : precautionary question

I have an old grids coming that uses 5 volts. I added a 5 volts rail to my case using what I had on hand (a 7805 with a 100uF cap on the input and 10uF on the output) and I’m getting 5.1 volts. Will this fry the grids?

thanks for your help

The voltage can go up to 5.5V.
