REGULATOR VOLTAGE DETECTION CIRCUIT AND SEMICONDUCTOR DEVICE

Provided is a regulator voltage detection circuit that can suppress a circuit area and current consumption inside the semiconductor device. A regulator voltage detection circuit of the disclosure outputs a detection signal indicating a voltage change of a regulator voltage output from a regulator circuit based on a reference voltage. The regulator voltage detection circuit includes a load element and a comparator. The load element includes a first terminal and a second terminal. A current is supplied from a constant current circuit to the first terminal. The second terminal receives the regulator voltage. The comparator includes a first input terminal connected to the first terminal and a second input terminal receiving the reference voltage. The comparator outputs the detection signal.
