<p><P>PROBLEM TO BE SOLVED: To easily change the variation of the voltage value of a supply signal that can be generated by a single power supply unit. <P>SOLUTION: As a result of a signal path being connected to an input terminal 36 to allow a first intermediate signal from a power-side regulator 20 or another external signal that does not pass through the power-side regulator 20 to be selectively input into any supply-side regulator 30, a supply signal can be generated on the basis of the signals. Therefore, as a result of the relevant supply-side regulator 30 being connected to a signal path by which the other external signal is input, a supply signal having a voltage value differing from that when the first intermediate signal is input can be generated. As a result of the signal to be input into the supply-side regulator 30 being changed, only the voltage value of the supply signal generated by the supply-side regulator 30 is changed. Therefore, the variation of the voltage value of the supply signal that can be provided as a power supply unit 1 can be changed. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
