linear regulators

A linear regulator is a device that maintains a constant voltage level for electronic circuits by adjusting its internal resistance. It works by drawing excess power as heat to ensure the output voltage stays steady, even if the input voltage varies. This makes it simple, reliable, and low-noise, ideal for sensitive electronics. However, because it dissipates extra energy as heat, it’s most suitable for applications with modest voltage differences and power needs. Essentially, it acts like a precise valve, letting just the right amount of electrical energy pass through to keep the connected devices operating smoothly.
