PURPOSE: A power supply apparatus for an electronic control system of an automobile is provided to be capable of being simplified in the structure by unifying the power supply supplied to the electronic control system. CONSTITUTION: The power supply apparatus comprises a regulator(10), an electric control system driving unit(20) and a reset signal generator(30). The regulator(10) stabilizes a battery voltage(B+) to supply a standby voltage(Vcc) for a micro controller(50) and a voltage(Vcc) for driving the electric control system. The electric control system driving unit(20) supplies the voltage supplied from the regulator(10) to the electric control system during an engine is driven. The reset signal generator(30) generates a reset signal for resetting the micro controller in initial driving timing of the engine.
