CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the
device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
+
150°C max junction temperature is for information purposes only. In reality, the current foldback feature will prevent the junction from rising above the
typical temperature of +110°C.
