Note 2: The maximum allowable power dissipation of any T A (ambient temperature) is P D(max) = (TJ(max)–TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature, and the regulator will go into thermal shutdown. Note 3: The UM1650/UM1750 is tested and specified under pulse load conditions such that TJ≈TA. Specifications over the – 40℃ to 125℃ operating junction temperature range are assured by design, characterization and correlation with statistical process controls. Note 4: This IC includes overtemperature protection that is intended to prot ect the device during momentary overload conditions. J unction temperature will exceed 125 ℃when overtemperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability.
