I would recommend following the circuit for regulated power supply. The use of a metal film 20 ohm resistor will also provide a little power protection should the device or the wiring short. The capacitor on that line will also kill some of the noise that might be present with all the brush tye motors running close by. The pullup load resistor may not be needed with the input circuitry of the RC.
