I have seen this question posted before, almost 4 years ago, but there was no answer posted. Still, TI sent me to this site anyway when I tried to get an answer directly from them.
Has anyone used the TL4051 adjustable part as a 1.2V reference? It appears from Figure 2 in the datasheet that the Anode can simply be connected directly to the feedback then the part will act as a 1.2V Zener, i.e. the source V from Figure 2 would then be zero Volts.
Has anyone actually done this?
