Abstract
PURPOSE:To change an operating current, by arranging transistors in impedance elements, constituting a power source circuit, to put the transistors ON/OFF. CONSTITUTION:An integral circuit 4 consists of a power source circuit 1, a load circuit group 2 and a control circuit 3. In the power source circuit 1, a switch S1 is provided in series to an impedance element Z1 while another switch S2 is provided in parallel to the element Z2. The switch S1 is put ON and the switch S2 is put OFF when the circuit is operated whereby a predetermined voltage Vp, determined by both elements Z1, Z2, is generated. On the other hand, the switch S1 is put OFF and the switch S2 is put ON when the circuit is waiting whereby the voltage Vp is kept in the potential of B. In this case, the switch S1 is being put OFF, therefore, the current consumption of the power source circuit 1 becomes zero.
