If I am using a voltage regulator to bring a voltage down from 9 to 5

The short answer is yes.

You don't tell us if you have only this one IC.

If you have a regulator and a single IC, then you should have the bulk output capacitor on the regulator and a 0.01 - 0.1uF cap *at the power pins* of the TTL device.
