Hi Team,
The current adjustment configuration is as follows
Remove D100
Add Q3, D18, D19, D17,R31
Q3 Vgs Min voltage= -18V
Why Zener diode D18, D19 does not clamp the voltage below -12V?

Hi Allen,
Thanks for reaching out!
May I know which Zener diode you applied? If it is 12V Zener, it could be its characteristic on voltage clamping and you may try one with lower clamping voltage
