ABSTRACT:
A voltage regulator has a phase inverter and a phase compensating condenser between an input differential amplification stage and an output voltage regulating stage, the input differential amplification stage compares a feedback voltage proportional to an output signal with a reference voltage so as to supply a first control signal representative of elimination of a difference between the output voltage and a target voltage level through the phase inverter to the output voltage regulating stage, and the phase compensating condenser transfers high-frequency noise components from the output node of the output voltage regulating stage through the phase inverter to the input node of the output voltage regulating stage, thereby eliminating the high-frequency noise components from the output voltage.
