●Thermal Design
When using at temperatures over Ta=25℃, please refer to the heat reducing characteristics shown in Fig.29 through 31. The IC
characteristics are closely related to the temperature at which the IC is used and if the temperature exceeds the maximum
junction temperature Tj
long-term operating reliability, it is necessary give sufficient consideration to IC heat. In order to protect the IC from thermal
damage, it is necessary to operate it at temperatures lower than the maximum junction temperature Tj
