(Note 2) TO252-3: Derate by 9.6mW /C when operating above Ta = 25C and when mounted on glass epoxy board with dimensions =70mm x 70mm x 1.6mm. 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.
