Note 2: The is tested and specified under pulse load conditions such that T J T A. Specifications over the 40 to 125 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 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 P DMAX = (T JMAX - T A )/ θ JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown. Rev.01 Dec /19
