Abstract
A digital low-dropout (LDO) regulator may include: an LDO core configured to select a control mode based on a state of an output voltage of the digital LDO regulator provided to a load block and to output a control code based on the control mode; and a plurality of power transistors configured to control supply current supplied to the load block based on the control code. The control mode may include a first mode and a second mode for changing the supply current faster than in the first mode. The LDO core may be configured to perform a step-back operation to re-output a previous control code output at least one cycle ago and operate in the first mode based on the state of the output voltage corresponding to the first mode being detected while operating in the second mode.
