Linear Voltage Regulators

A linear voltage regulator is a simple device that maintains a steady voltage level output from a higher, fluctuating input voltage. It works by continuously adjusting its internal resistance, discarding excess voltage as heat, to keep the output stable. This ensures electronic components receive a consistent power supply, improving performance and safety. Linear regulators are straightforward, quiet, and efficient for low to moderate power applications, making them popular in audio equipment, circuits, and where clean, stable voltage is essential.
