description A method for improving safety of voltage regulator is disclosed. In order to improve safety of a voltage regulator, a MOS-FET is disposed on a source power lane that receives power supplied from a DC power supply. A set of voltage regulators is connected to a set of fork power lanes, correspondingly, branching off from the source power lane. PTC thermistors are disposed on a surface or in the vicinity of semiconductor chips of the voltage regulators. When temperature at any one of the PTC thermistors increases, a protection controller turns off the MOS-FET. When temperature detected by a temperature sensor incorporated within the semiconductor chip has increased, each of the voltage regulators turns off the MOS-FET via a base management controller.
