Hi,
The input voltage of the pcb I want to design can be 12vdc or 24vdc. I want to get a constant 12v as the output voltage. So if the input voltage is 12v, the output voltage is 12v, if the input voltage is 24v, I want to get the output voltage again 12v. How can I do it ? Is there such an product?
TechCB:
I don't know the specs of your design (current, power, etc.)… But take a look at the LM7812C datasheet, this voltage regulator may help you with your design.

We're going to need more info !! Lots of possibilities, depending on your requirements. #1 What current !!? #2 What output variation ? +/- 5% 10% ? #3 What type of load ? Resistive / Inductive / Capacitive ?

but for 12v output , Vin must be (14.5 ≤ VIN ≤ 27) in your product.

12v or 24v input, 12v at least 1.5A output, maybe additional 5v 1a output. Actually 12v output for sevaral opamps and darlington bjts.
