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 = 20 W).
2. CADJ, when used, is connected between the adjustment pin and ground. © 2002 Fairchild Semiconductor Corporation
