In the case of exceeding Ta > 25°C, 4.6mW should be reduced per 1°C (Mount on 50mm x 58mm x 1.75mm Glass Epoxy Board)
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
