I'm looking for a parameter telling me the maximum allowable voltage on the reference input of the TL431. It only gives me the max. input current. There is no reference voltage parameter under Absolute Max Ratings.
What if I wanted to use it as a voltage comparator where the reference voltage will exceed 2.5V, e.g. 15V? It should work, question is, how long....
I attached a diagram. Ignore the transistor type and the absolute resistor values, I didn't even check the transistors parameters... it's only about the max voltage on the ref input.
Any ideas?
Thanks
