400nl - TPTK no good in this 3bet pot?

[BlackAMEX]

Villian is a decent 25/15/3 reg. No specific reads apart from that.

Turns out I actually flop a legit hand for once in a 3bet pot in position! This is either the 1st or 2nd time Ive 3bet him this session, so he has no reason to think I'm getting out of line.

Flop bet is a little small (usually about 77 is right for me), but I dont know whether that's an issue or not?

Villian's ch/push here is pretty strong, and really all I beat in his range is a hand like AKcc, which still obv has very strong equity over me here.

I folded and felt good about it. Correct play?
