BIAS CIRCUIT

摘要

PROBLEM TO BE SOLVED: To provide a regulator circuit with an improved noise margin.SOLUTION: A regulator circuit 150 includes a bias circuit 110 generating reference voltage VREF based on potential difference between a first power supply terminal and a second power supply terminal, and a voltage regulator outputting potential to an output terminal based on reference potential input from the bias circuit. A bypass capacitor is provided between the power supply terminal and a node to which a gate of a transistor included in the bias circuit is connected.
