Note 2: The UM1550/1560 is tested and specified under pul se load conditions such that T J≈TA. Specifications over the – 40°C to 125°C operating junction temperature range are assured by design, characterization and correlation with statistical process controls. Note 3: This IC incl udes over temperature protection that is intended to prot ect the device during momentary overload conditions. Junct ion temperature will exceed 125 °C when over temperature protection is active. Continuous operation above the specified maximum operating junction temperature may impair device reliability. Note 4: The maximum allowable power dissipation of any T A (ambient temperature) is PDMAX= (TJMAX-TA)/θJA. Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown.
