How to Build an Adjustable Voltage Regulator using 7805 - Step-by-Step Guide

In this tutorial, we will show you how to build an adjustable voltage regulator using the popular 7805 IC. The 7805 is a three-terminal positive voltage regulator that can provide a fixed output voltage of 5 volts with a maximum output current of 1 ampere. However, with a few additional components, it can also be used to build an adjustable voltage regulator that can provide a variable output voltage.

In this step-by-step guide, we will walk you through the process of building an adjustable voltage regulator using the 7805 IC. We will explain the theory behind voltage regulation and show you how to select the appropriate components for your circuit.

By the end of this tutorial, you will have a fully functional adjustable voltage regulator that you can use in a variety of electronic projects. So, whether you are a beginner or an experienced electronics enthusiast, this tutorial is perfect for anyone who wants to learn how to build an adjustable voltage regulator using the 7805 IC.
