Overview of Low Drop-Out (LDO) RegulatorsLow Drop-Out (LDO) regulators are a specialized type of linear voltage regulator designed to provide a stable output voltage with minimal input-output voltage differential, known as dropout voltage. This feature is particularly advantageous in applications where the input voltage is only slightly higher than the desired output voltage, such as in battery-operated devices. LDOs are prevalent in various electronic applications, including smartphones, tablets, and other portable electronics, where power efficiency and compact design are paramount.
