We may have hit the limits of context here. :-)
Let me explain:
Solid state voltage regulators are indeed very well temperature
compensated for their intended purpose. That purpose is to maintain
as tight a voltage regulation as possible under a wide variety of
operation conditions including temperature swings.
But we don't want that in our LBC heater gauge circuits. We want the
stabiliser's average voltage to vary inversely with ambient
temperature so it offsets the errors inherent in heater type gauges.
Sorry for the confusing terms.
Cheers!
