Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stres s ratings only, and functional operation of the device at these or any other conditions b eyond those indicated under “Recommended Operating Conditions” is not implied. Exposure to “Absolute Maximum Ratings” for extended periods may affect device reliability. 5. The junction temperature rise is given by T RISING = PD*θJA, where PD is the power dissipated by regulator, θJA is the thermal resistance from junction of the die to the ambient temperature; The junction temperature, TJ is given by TJ = TA+TR, where TA is the ambient temperature. 6. DC voltage rating, for short period of spike voltage, the minimum voltage rating is -1V, in 20nS.
