4 / 28 page MC78XX/LM78XX/MC78XXA 4 Electrical Characteristics (MC7808) (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.
