Given that you just sat down, I might fold it here. It's the sort of situation where you really need a read as to whether this player will shove with TPTK or some other weak hand.

However, I also agree with the other commenter that you could have gone all-in in response to the initial flop bet, because at that point Villain's range is wider.
Folding top pair is against the law at .02/.05. You should know that, Lawdude!
