PROBLEM TO BE SOLVED: To provide a power circuit capable of preventing functional stall of an on-vehicle apparatus which possibly occurs at starting from an idling stop with a simple configuration.SOLUTION: A power circuit (2) in which a circuit group in need of initialization that requires the initialization processing at starting and a circuit group without the need for initialization that requires no initialization processing at starting coexist, and which is mounted on an on-vehicle apparatus (1) operated by receiving power from an on-vehicle battery includes: a first regulator (21) and a second regulator (22). The first regulator receives the power from the on-vehicle battery and converts the received voltage into a preset first supply voltage to supply the voltage to the circuit group without the need for initialization. The second regulator receives the power from the on-vehicle battery and converts the received voltage into a preset second supply voltage which is preset to be lower than the first supply voltage to supply the voltage to at least the circuit group in need of initialization. |
