(Note 2) If mounted on a standard ROHM 4 layer PCB (copper foil area: 70 mm × 70 mm) (Standard ROHM PCB size: 70mm × 70 mm ×1.6mm) Reduce by 9.6 mW / °C (Ta ≥ 25 °C) 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.
