Abstract
A regulator device includes: a power input terminal; a power output terminal; a plurality of regulators each including an operating FET and a monitoring FET to be driven together with the operating FET, the plurality of regulators being arranged in parallel between the power input terminal and the power output terminal; and a controller configured to drive the operating FET and the monitoring FET included in one of the regulators, when the controller determines whether the monitoring FET included in the one of the regulators have degraded, the controller configured to stop driving the operating FET and the monitoring FET included in the one of the regulators and configured to drive the operating FET and the monitoring FET included in another of the regulators.
