kindly help, i'm a beginner in analog circuit field, how do i start project, basic to understand project.
 

A zener diode is the basic voltage regulator. It is capacitor-less.

Many voltage regulator circuits use a zener diode.

An internet search will turn up lots of articles and demonstrations.

Also at the bottom of this webpage, see a list of related thread titles at this forum.
 

It is depends on input supply. If you are using a properly regulated & filtered voltage then no capacitor is required at the input side but it is good practice to use the filter capacitor in the regulator circuit.
