NL25 - JJ overpair on the flop

[customer_nr1]

No reads on villain. My hand could be good if his range is QQ+, AK, but if we get all-in here I am most likely beaten. So I am not commited. A raise would turn my hand into a bluff I guess. But if I call down to the river that could cost me my stack.
Is folding on this flop considered too tight? Or call this small bet and fold on turn if he fires again?

Btw is it likely that villain's range is looser than that? AQ,TT or other things? He basically just minraised me PF.

Thanks for the replies!
