LDO (Low Dropout Regulator)

An LDO (Low Dropout Regulator) is a type of electronic device that provides a steady voltage to electronic circuits, even when the input voltage is very close to the desired output voltage. Unlike traditional regulators, LDOs can operate with a small difference (dropout voltage) between input and output, making them efficient for powering sensitive components with minimal energy loss. They are commonly used in compact electronics to ensure precise voltage levels, improve performance, and reduce heat generation, especially when power supply variations are limited.
