Abstract
A low dropout (LDO) regulator is configured to generate first to nth output voltages, where n is a natural number greater than or equal to 2, and each of the first to nth output voltages corresponds to a reference voltage. The LDO regulator includes an amplifier configured to generate an error voltage based on the reference voltage and a first output voltage of the first to nth output voltages, a trimming control circuit configured to generate first to (n−1)th trimming signals based on the first to nth output voltages, and an output buffer circuit configured to generate the first to nth output voltages based on the error voltage and the first to (n−1)th trimming signals.
