I have various electronic items on board which are rated at 14V and
16V DC max. I am fitting a 20" LCD TV this winter and that is rated
at 16V max. Although so far I've not had a failure I'm concerned at
spike protection and voltage regulator failure giving high voltages.
I had considered some hefty 16V zeners with suitably fused feeds to
act as protection.
Could low drop-out regulator ICs help to regulate down to a nominal
12V, but how do they work if the input voltage drops below 12V?
Any suggestions welcome. I am off in the spring on an extended trip
of around 5 years duration and am currently preparing for as many
eventualities as possible.
