I am looking for a VC that can handle at least 25V input.

I search digikey, and I found some that stated that it could handle up to 30V but when still looking at the datasheet, it shows values for a 5V Vcc.

I would like to know the values with 30V and was wondering if anyone knew where i could find a VC that shows value of 30V.

Thanks,

your supply voltage must be higher then the input voltage.
are you looking for this:

An alternative might be to use resistors to make a voltage divider. Apply the 30 volts across a 1 meg and 9 meg resistor (in series) and 3 volts will be the voltage drop across the 1 meg resistor.

you talking about supply or input?
