Easiest way to regulate a 12 V battery to regulated 12 V?
Admittedly, applying regulation solves that problem by nailing the voltage down to something that''s supposed to work, but the thing is, voltage regulation gets complicated when the source and the output voltages are closer than about 2 volts, because regulators need some headroom to work with. Automotive batteries nominally sit around 13.8V; worryingly high if …
