Making Adjustable Regulators For The Purposes Of Daily Electronics Hobby

In the world of electronics, of course, we need a variety of voltages needed for different purposes, but do we have to provide many power supplies for each of these purposes?

Yes, of course not, because with only one voltage source we can get these needs, the way is to make our own Adjustable Regulator.

Below I make an Adjustable Regulator with a voltage range ranging from 2V to 15V, with a current that can be adjusted to the maximum according to the adapter / smps used.

I use smps Laptop charger with a voltage specification of 19V and a current of 3A.

Here's the Scheme, Layout and finished image
