Electrical Characteristics (KA79L08A) (Continued)
(VI = -14V, IO = 40mA, CI = 0.33
µF, CO = 0.1µF, 0°C ≤TJ ≤ +125°C, unless otherwise specified)
Note
1. 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.
