A semiconductor integrated circuit apparatus and an electronic apparatus having a power control function configured from power control MOS transistors in such a manner that leakage current and on resistance at the time of cut-off is sufficiently small in actual use. Semiconductor integrated circuit apparatus is comprised of a CMOS logic circuit, a second pseudo power supply line connected to a low potential side power supply terminal of the CMOS logic circuit, and a power control NchMOS transistor connected across a second pseudo power supply line and a low potential side power supply line, with the substrate and gate of power control NchMOS transistor being electrically connected. The gate and the substrate may also, for example, be connected via a current limiter utilizing, for example, a source follower of a depletion type NchMOS transistor.
