It employs internal current limiting, thermal shut-down and safe area compensation. Note: 1. 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 = 15W) 2. CADJ, when used, is connected between the adjustment pin and ground.
