The device should not be operated at these limits. The parametric values defined in the Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The “Recommended Operating Conditions” table will define the conditions for actual device operation. Electrical Characteristic (VI - VO 5V, IO 0.5A, 0qC d TJ d 125qC, IMAX 1.5A, PDMAX 20W, unless otherwise specified) Note 2: Load and line regulation are specified at constant junction temperature. Change in VD due to heating effects must be taken into account separately. Pulse testing with low duty is used. (PMAX 20S) Note 3: CADJ, when used, is connected between the adjustment pin and ground.
