Abstract
Disclosed is a power supply semiconductor integrated circuit including: a power supply input terminal; a power supply output terminal; a ground terminal; a first external terminal to which a second terminal of a first capacitor is connected; a second external terminal to which a second terminal of a second capacitor is connected; a first detector which detects a voltage of the first external terminal; a second detector which detects a voltage of the second external terminal; a first switch between the first external terminal and the ground terminal; and a second switch between the second external terminal and the ground terminal. The first switch disconnects the second terminal of the first capacitor from ground potential upon receiving a signal from the first detector, and the second switch disconnects the second terminal of the second capacitor from ground potential upon receiving a signal from the second detector.
