KA78XXE/KA78XXAE Rev. 1.0.1

Electrical Characteristics (KA7818E) (Continued)

Refer to test circuit, 0°C < TJ < 125°C, IO = 500mA, VI = 27V, CI = 0.33µF, CO = 0.1µF, unless otherwise speciﬁed.

Notes:

15. 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.

16. These parameters, although guaranteed, are not 100% tested in production.
