Abstract
According to an aspect, a low dropout (LDO) voltage regulator includes a differential amplifier, a pass transistor coupled to an output of the differential amplifier, where the pass transistor is configured to provide an output voltage of the LDO voltage regulator, and a soft-start circuit coupled to the differential amplifier. The soft-start circuit is configured to adjust a soft-start driving signal to control a slope of the output voltage based on the output voltage during a start-up operation of the LDO voltage regulator.
