(Note 1) Reduced by 4.7 W/°C over 25°C, when mounted on a glass epoxy board (70 mm x 70 mm x 1.6 mm).
(Note 2) Must not exceed Pd.
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. 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.
