How much is the current that you need?
If your current is low, you can use lm7812 as well as.

Maximum rated input voltage is 35V for a LM7812

Dear friends
Hi
Prototyp_V1.0 is right.
But for this application you can use a simple linear regulator ( with op amp and emitter flower ) and a simple feed back , if your current is not high.
Best regards
