Abstract
PURPOSE: To simplify the construction of a voltage sequential circuit suitable for use in a data transmission circuit in which the order of sequential inputs of power sources is the reverse of the order of sequential cuts of power source, by providing a voltage regulator which effects cascade connection in accordace with the order of input of power sourse, and a switch for controlling the secondary input of power source by output of the voltage regulator which is previously inputted.
CONSTITUTION: A power sourse 10 of alternating current is supplied to a constant voltage power source apparatus 30 through a switch 20. The constant voltage source apparatus 30 generates a prescribed direct current voltage Vs to supply it to a voltage regulator 40. The voltage regulator 40, the input of which is the direct current voltage Vs, generates a direct current voltage V1 to supply it to a load circuit 45. When the direct current voltage V1 has beene stablished the switch 50 becomes on and supplies the direct current voltage Vs to a load 55. By the above construction, a sequential circuit of power source is provided in which the order of inputs of power source becomes from V1 (the output of the voltage regulator) to V2 (the voltage supplied to the 1 and 55), and the order of cuts of power source becomes from V2 to V1.
