Introduction

As the world is moving forward, technology is also moving upwards. But electronic gadgets and equipment are getting smaller. Because we humans want everything in the palm of our hands and therefore, designers are trying to shrink the electronic circuits as possible. These electronic circuits help to build small size compact and portable devices. So, for this purpose designers have already made the SMD voltage regulators which we are going to study in this article. Thus this article is about the 5 Amp SMD Voltage Regulator where we study different 5A regulators.
