Note 2: The UM3730 is tested and specified under pul se 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 3 : This IC includes over temperature protection that is intended to prot ect the device during momentary overload conditions. Note 4: The maximum allowable power dissipation of any T A(ambient temperature) is PDMAX = (TJMAX - TA)/ θ JA. Exceeding the maximum allowable power dissipation will result in excessive die temperature and the regulator will go into thermal shutdown.
