(Note 1) Reduce by 5.33mW/°C over 25°C, when mounted on 2-layer PCB of 114.3mm × 76.2mm × 1.6mm.
PCB incorporates thermal via. Copper foil area on the reverse side of PCB : 74.2mm×74.2mm
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.
