Abstract
In a conventional electronic device, it is difficult to passively diagnose disconnection of an external capacitor added to an output terminal of a regulator circuit. An electronic device in this embodiment includes a regulator circuitthat outputs a constant voltage while external power supplied from the outside is input thereto, an external capacitorconnected to an output terminal of the regulator circuitas an external component, an oscillation detectorthat detects an oscillating state of the output voltage of the regulator circuit, and a failure determination unitthat outputs a failure signal when the oscillation detectordetects the oscillating state of the regulator circuit.
