The good news is that probably most of the noise from the steppers will stay on the 12 volt side of the regulator. But you will need a filter capacitor on the 5 volt side of the regulator. The value of that capacitor will depend on the noise level and I am not able to comment on that. But it may be specifier in the device data sheet.
