Especially right attention has to be paid to aluminum electrolytic capacitor because ESR changes greatly at the time of the low temperature and output ripple voltages increase.

Please set a capacitor near the module. If a capacitor is far from it, there is some case that output ripple voltage or radiation noise become big. Be sure to use fuse for safety. Please take the start-up time of input voltage within 20ms. There is fear of destruction by overinput current if it is more than 20ms. www.rohm.com 1/1 2012.05 - Rev. A 2012 ROHM Co., Ltd.
