Trevor:
Are they temperature compensated to provide a *constant* output voltage over
a wide temperature range, or is the compensation designed to *vary* the
voltage over the required temperature range to match the requirements of the
gauge inaccuracies over the same temperature range. If the compensations
maintains a constant voltage, then, as Tom pointed out, the gauges will be
inaccurate as the temperature changes.
Unless the regulators were specifically designed to be used with bi-metal
gauges, they wouldn't be effective. In other words, as the temperaure drops,
the output voltage should rise to compensate, not remain the same.
