`
`ABSTRACT OF THE DISCLOSURE
`
`In the voltage supply circuit, a reference voltage generating circuit
`
`generates a reference voltage. An operational amplifier circuit generates
`
`an output voltage on the basis of the reference voltage. A selection circuit
`
`has at least two first terminals to select one of the first terminals and to
`
`generate a passed output voltage representing the output voltage passed
`
`through the first terminal selected. A second terminal receives the passed
`
`output voltage and is capable of outputting the passed output voltage to a
`
`1O
`
`load circuit. A detection circuit detects a magnitude of the passed output
`
`voltage and generates a detection voltage. The selection circuit selects a
`
`voltage corresponding to the passed output voltage generated from among
`
`at least two of the detection voltages and generates a detection voltage
`
`representing the detection voltage selected. The operational amplifier
`
`15
`
`circuit decreases the difference between the reference voltage and the
`
`selected detection voltage.
