2 / 6 page KA317 2 Absolute Maximum Ratings Electrical Characteristics (VI-VO= 5V, IO= 0.5A, 0°C ≤ TJ ≤ +125°C, IMAX = 1.5A, PDMAX = 20W, unless otherwise specified) 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 = 20W) 2. CADJ , when used, is connected between the adjustment pin and ground. 3. These parameters, although guaranteed, are not 100% tested in production.
