Abstract
A constant-current FET functions as a constant current element by application of a constant voltage to the gate thereof. A first switch FET is disposed between the constant-current FET and a power supply without another switching element being disposed between the constant current FET and an output terminal. A second switch FET that performs an on/off operation in association with an on/off operation performed by the first switch FET is connected between the output terminal and ground.
