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

Data sheet says max cathode-to-anode voltage is 36V. What if VCC = 50
I use these and they're good parts. 50V will blow it up--be careful of

V, as in this cheezy drawing is trying to show. R1 and R2 set the
output voltage at the emitter. R3 limits the current to the cathode

wow, that drawing didn't look very good in my mail client, but if you
cut and paste into kedit it looks reasonable. :)
Looks good in my newsreader client :^)

Hi all,
I'm replacing an old drive and since my distribution of Fedora is so
old I'm purchasing a new dvd. Then I thought before I do, since I use
it for the geda software, why not get the same distribution most of the
geda gurus use.
At the risk of starting a major debate

Or set up your mailer to use a fixed-width font..
Yes, that was it - thanks.
I suspect this TL431 isn't a good device for my app. I have an LM317 to
give me around +12V for bootstap voltage

Larry,
I couldn't tell you since I never updated geda after installation.

If you're using gtk the file to change is gpcb-menu.res
A little confusing and not documented, but it works.
Probably the best thing to do would be to have separate sections in
the same pcb-menu.res.
