[TR] gas gauge and voltage regulators

Polyfuses are cheap. As I said, not as simple as a single polarity regulator but it can be done. I just had a thought of how to do it with only one zener and using the spare opamp gate as a conditional inverter but that adds still more complication. The rest is left to the student - as my textbooks used to say.

Very clever. But I
would still call that two separate regulators (ZR1 and ZR2), you've just added a
voltage follower to the output.

No over-current protection either.
