JSR03, 05 questions

[peranders]

12 V, LM329
*************
R4, R5, R6 not used
R3 = 2.2 - 5-6 k choose 2.2-3.3k if you can.


5 V out, LM336
*************
Observe that anode and cathode is swapped compared to LM431.

R3 = 1k

Using R11 may work. If not, use R12.



Sense
*********
If you don't plan to use the sense function you can omit R15, R16, C13, C14

An error in the JSR05 schematic, thanks I will fix that.
