A load driving device according to an exemplary aspect of the present invention includes: an output transistor coupled between a first power supply line and an output terminal; the output terminal being configured to be coupled with a load; a driver circuit that controls conduction/non-conduction of the output transistor; a compensation transistor that is coupled between the output terminal and a second power supply line, and becomes conductive when the driver circuit renders the output transistor non-conductive and when a potential of the second power supply line reaches a predetermined value or greater, to maintain a non-conduction state of the output transistor; and a first resistor coupled between the second power supply line and a back gate of the compensation transistor.
