According to the present invention, after a bias circuit ( 20 ) starts, a startup circuit ( 10 ) is isolated from the bias circuit ( 20 ) according to a bias voltage generated on an isolating voltage node (V 2 ) from the bias circuit ( 20 ) to the startup circuit ( 10 ), and steady current consumption can be prevented in the startup circuit ( 10 ).
