PROBLEM TO BE SOLVED: To provide a power circuit device that can suppress heat generation from a regulator IC without using a power limiting resistor or a heat sink. SOLUTION: The power circuit device 2 comprises a filter 4 for noise removal from a general purpose DC power source part 1. The power circuit device 2 comprises the first stage regulator circuit part 5 for the first stage DC voltage conversion, the second stage regulator circuit part 6 for the second stage DC voltage conversion, the nth stage regulator circuit part 7 for the nth stage DC voltage conversion for outputting a DC voltage of a predetermined voltage to a load circuit part 3, and protective diodes 8 for circuit protection upon a reverse input-output bias.
