Regarding using the el'cheapo voltage reference: What startup and shutdown conditions would that cause ? Would it cause any overshoot at startup and shut down ? I can see how it would work well when everything is in it's stable state but I'm unsure about other states - I also want to be able to use this on laser diodes which are very delicate.
Is there any reason that I'm missing why I couldn't use 10K resistors instead of the 100K resistors ? I have lots of 10K's ...
I'm building something similar to this only using 3x 1084's in parallel. In the last example attachment I see the 1.25v reference. Is this connected to a 1.25v reference IC not in the schematic, or is it just a labeling of one net and they are to be connected together?
