reducing characteristics
When using at temperatures over Ta=25℃, please refer to the power dissipation shown in Fig.20 through 22.
The IC characteristics are closely related to the temperature at which the IC is used, so if the temperature exceeds the
maximum junction temperature TjMAX, the device may malfunction or be destroyed. The heat of the IC requires sufficient
consideration regarding instantaneous destruction and long-term operation reliability. In order to protect the IC from thermal
damage, it is necessary to operate it at temperatures less than the maximum junction temperature TjMAX.
Even when the ambient temperature Ta is a normal temperature (25℃), the chip(junction) temperature Tj may be quite high,
so please operate the IC at temperatures less than the acceptable loss Pd.
