Debounce on input so map address lookup doesn't happen with every keystroke

I’m struggling to find the debounce option, I know it’s there somewhere!

I have an input box where the value is used on a Google Map Address attribute but, to keep the API charges as low as possible, I don’t want it to look up after every keystroke so I’m thinking the debounce option is the way to go but I can’t find it anywhere. Can any point me in the right direction?
