Electrical Characteristics (KA7812AE)

Refer to the test circuit, 0

°C < TJ < +125°C, IO = 1 A, VI = 19 V, CI= 0.33 μF, CO = 0.1 μF, unless otherwise specified.

Notes:

27. Load and line regulation are specified at constant junction temperature. Change in VO due to heating effects must

be taken into account separately. Pulse testing with low duty is used.

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