A Linear Regulator is a basic but important electronic component that helps control and maintain steady power in electronic devices. Think of it like a tap that controls water flow - it takes higher electrical voltage and reduces it to a steady, lower level that's safe for electronic devices. You'll often see this term in resumes of electronics repair technicians who work on power supplies in computers, TVs, or other electronic equipment. It's also sometimes called a "voltage regulator" or "power regulator."
