I love to cook with wine. Sometimes I even put it in the food.

Nice.

That sure is nice. The only fly in the ointment would be that the 3046
is now around 30c or so while the LMV431 costs half that and has it all
in there. But I always liked the 3046. Jim, since you designed so many
chips, did you do this one as well?

Regards, Joerg.

No. Didn't do 3046 or any TL/LMV, but I've literally done hundreds of
BandGaps over the years.

The CA3096 was a more attractive chip to me, with three npn and
two pnp transistors. I used this RCA chip in the early 70s to
make a micropower (5uA) band-gap voltage reference, and we made
many hundreds of them, in deep-sea oceanographic instruments.

Thanks,
