Haha! Transformer, diodes and a capacitor.
Only if you don’t count diodes as ics.

Go for IC 7809.

What value of zener diode and sereis resistance should be used to produce the desired output?
I don’t know the load resistance. What type of voltage regulator can be used if I don’t know the load resistance?
