4 / 26 page KA78XXE/KA78XXAE 4 Electrical Characteristics (KA7808E/KA7808ER) (Continued) (Refer to test circuit, 0 °C < TJ < 125°C, IO = 500mA, VI =14V, CI= 0.33µF, CO=0.1µF, unless otherwise specified) Note: 1. Load and line regulation are specified at constant junction temperature. Changes in VO due to heating effects must be taken into account separately. Pulse testing with low duty is used. 2. These parameters, although guaranteed, are not 100% tested in production. Parameter Symbol Conditions KA7808E Unit Min. Typ. Max.
