(Note 4) Mounted on 70mm x 70mm x 1.6mm glass epoxy board. Reduce 5.5mW per 1C above 25C. (Note 5) P is a value in the package unit. Reduce 9.0mW per 1C above 25C. D Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings. www.rohm.com TSZ02201-0RCR0GZ00120-1-2 2014 ROHM Co., Ltd.
