Linear voltage regulators, including Low Dropout (LDO) regulators, provide a simple and reliable method for maintaining a stable output voltage from a higher input voltage. LDO regulators are designed to operate with a minimal voltage difference between input and output, making them ideal for low-voltage, high-efficiency applications. Commonly used in portable electronics, IoT devices, automotive systems, and industrial equipment, LDOs offer low noise, fast response, and excellent power supply rejection, ensuring stable operation of sensitive analog and digital circuits.
