A voltage regulator keeps output voltage constant so your electronics get steady, predictable power regardless of input or load changes. Every circuit you own depends on a steady power supply. When voltage sags or spikes, chips malfunction, screens flicker, and components wear out early. That stability is exactly what voltage regulators exist to provide. Understanding […]
