<p>At the time of adjusting a voltage, a selector (23) outputs data (D01, D1) received from the external to a current adjusting section (24). A voltage (VOUT) changes when the current adjusting section (24) changes a current (I01) corresponding to the data (D1). The data (D1) obtained when the voltage (VOUT) is decided to be a certain value becomes data (D2) to be stored in a storage section (22). In normal operation, the selector (23) gives the data (D2) outputted from the storage section (22) to the current adjusting section (24). Therefore, even in the normal operation, a power supply circuit (1) can output the highly accurate voltage (VOUT). Thus, a semiconductor device which can output the highly accurate voltage and a power supply device provided with such semiconductor device are provided.</p> |
