I am trying to understand the TL431.
I have a 100k 10K trim pot and 30K resistor in series.
The supply voltage is 13.8 volts.
On the centre pin pf the trimmer I get a voltage range of 2.81 and 3.6 Volts
I want to know what the voltage that is on reference pin 1 of the tL431 switches on the TL431.
I have built this exact circuit with help in previous threads and now I cant get it to work.
