I am a newbie here and would appreciate the help. I need some help on a project...the answer is probably really simple, so please be patient.
I need to design a simple (and I mean simple) circuit that will receive a forward biased DC Voltage at the input ranging from 0-100VDC and the output needs to be kept at a constant 1VDC. The key is that the circuit can receive 0-100VDC without any damage but will only take a specific voltage range or exact voltage to pass current. What I mean is something for example that will take 0-20VDC without passing current and at 20VDC will pass current through. At 21VDC it will stop passing current. So it will be specific up to one certain voltage.
I know to use a voltage regulator to keep the output constant but I want something to keep the input inactive up to a certain voltage and then for it shut off again once it passess that threshhold.
Thanks.
