Abstract: A voltage regulator includes a pass unit configured to transfer an input voltage to an output node as an output voltage according to a control signal, a voltage dividing unit configured to divide the output voltage to generate the divided output voltage, an error amplifying unit configured to output a comparison signal based on comparing a magnitude of the divided output voltage with magnitude of a reference voltage, and a filter unit configured to filter noise included in the outputted comparison signal to generate the control signal. The filtered noise may correspond to noise included in the outputted comparison signal by transferring noise included in the input voltage to the error amplifying unit via the pass unit and the voltage dividing unit.
