This assembly is a bit tight in input voltage. On a boat or car, you need a regulator circuit capable of withstanding 40V and more.
There are big electrical pulses sometimes on the boat. With a regulator that only supports 18V, there is a real risk because the TVS diode with a threshold of 15V risks burning out, due to a lack of margin in relation to the voltage of certain alternators or chargers. There are also some chargers or MPPTs that have an equalization phase at more than 15V.
You really need a margin in input voltage with as much as possible an AEC-Q100 certified component.
