A clean linear supply prevents hum in audio transmissions.

A reliable is one of the most common requirements for electronics hobbyists and professionals. Whether you need to power LED strips, routers, audio amplifiers, battery chargers, or microcontroller projects like Arduinos and Raspberry Pis, a 5-ampere supply provides 60 watts of clean, regulated power. 12v 5a power supply circuit diagram

Building a is a rewarding project. For simplicity and low noise, the linear design using LM338 or LM317+2N3055 is ideal – just be prepared for heat and weight. For efficiency and compact size, the SMPS design with UC3843 is superior, though it requires careful transformer winding and PCB layout. A clean linear supply prevents hum in audio transmissions
