Abstract
Provided is a constant voltage output circuit having an output terminal and configured to supply power to a crystal oscillator circuit connected to the output terminal, the constant voltage output circuit, having: a bias current control circuit subjected to negative feedback control by an output voltage which is supplied from the output terminal. As a result, variation in the constant voltage output caused by variation in current from a constant current source is reduced.
