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.
