    Abstract: A voltage regulator includes a pass transistor generating an output voltage in response to a gate voltage, and an error amplifier circuit outputting the gate voltage. The error amplifier circuit includes a first input terminal receiving a first reference voltage level from a reference voltage generator, a second input terminal receiving a second reference voltage level from the reference voltage generator, a third input terminal receiving a first voltage level of a first end of a target circuit, a fourth input terminal receiving a second voltage level of a second end of the target circuit, and an output terminal that outputs the gate voltage generated based on the first reference voltage level, the second reference voltage level, the first voltage level, and the second voltage level. A potential difference of the first voltage level and the second voltage level is an operating voltage of the target circuit.
