Notice
* Take care not to cause interference due to wiring of IN- and OUT1. * Wiring need to be short to prevent carrying of the noise. If the noise is carried, insert a capacitor between IN+ and IN-. * In application of connecting the CT pin to GND, lock protection and restart function are not effective.
