Electrical Characteristics (KA78M24/KA78M24R)

(Refer to the test circuits, 0

≤ TJ ≤ +125°C, IO=350mA, VI=33V, unless otherwise specified, CI = 0.33µF, CO=0.1µF)

Notes:

*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.
