Note 2: The UM1550/1560 is tested and specified under pulse load conditions such that TJ≈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 includes over temperature protection that is intended to protect the device during momentary overload conditions. Junction 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 TA (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. ________________________________________________________________________ http://www.union-ic.com Rev.01 Nov.2015 4/13 UM1550/1560 Electrical Characteristics VIN= VOUT+1V, CIN=COUT=1µF, TA=25°C.
