Abstract

Provided is a multiple-voltage power supply apparatus which generates multiple power source voltages including a positive output voltage and a negative output voltage by using one input voltage. In the multiple-voltage power supply apparatus, multiple output voltages can be obtained irrespective of the input voltage, and an operating range in the input voltage can be easily widened. In addition, since the regulator is used to generate the positive output voltage, it is possible to obtain a voltage invulnerable to a switching noise.
