<p>In the present invention, when the conduction state of at least one of MOS transistors, that is, a PMOS transistor (P1) or an NMOS transistor (N2), is switched to an off state, a current to be applied to the MOS transistor with the conduction state being in the off state as the conduction state is changed to the off state is bypassed to a resistor element (R3, R4). Consequently, the current from the direct-current power supply is prevented from being directly applied to the MOS transistor with the conduction state being in the off state, so there is no need to increase the breakdown voltage of the MOS transistor. Thus, the manufacturing cost of this direct-current voltage output circuit (54a) can be minimized. At the same time, the circuit size of the direct-current voltage output circuit (54a) can be reduced.</p> |
