Hello,
I have used LM4040C10IDBZR shunt voltage reference to produce 10V from +15V but it is actually outputting 9.4V? this voltage needs to be a stable 10v.
to be honest I don't remember why I chose to put exactly 312ohm in there or if should i put a like voltage divider that makes 10v output...
Here a shunt voltage regulator circuit with two zener diodes
One zener diode Z give the reference voltage at the comparator for the feedback signal .
But I can't explain the role of the second zener diode Z1
I've to calculate Voltage Stability factor (Sv) .
Any Suggestion is welcome.
