Re: gEDA-user: TL431

If you can guarantee that R3 will always drop enough voltage, then you
should be fine.  But consider what your circuit is going to do on
power-up and power-down, and if there will be any voltage spikes.  If
you don't think your solution will cut it, you could add a zener diode
between ground and R2|TL431 .  That, however, would reduce the
accuracy of regulation at the top of R1.
