Does the input voltage need to be higher than 18 V?
Yes. A linear regulator needs an input voltage above its output by its dropout margin. Check the datasheet for the exact minimum input voltage.
Do I need a heatsink with this regulator?
A linear regulator dissipates the voltage difference as heat. A heatsink is recommended at higher currents or when the input-to-output difference is large.
