Abstract

See full text

A voltage regulator circuit includes a first amplifier, a second amplifier and a transistor. Respective first input terminals of the first and second amplifiers are coupled to a first reference voltage and a second reference voltage, respectively. A connection terminal of the transistor is coupled to a supply voltage. A control terminal of the transistor is selectively coupled to one of respective output terminals of the first and second amplifiers. When the control terminal of the transistor is coupled to the output terminal of the first amplifier, another connection terminal of the transistor is coupled to a second input terminal of the first amplifier to output a regulated voltage. When the control terminal of the transistor is coupled to the output terminal of the second amplifier, the another connection terminal of the transistor is coupled to a second input terminal of the second amplifier to output the regulated voltage.
