11 / 17 page KA79XX/KA79XXA 11 Electrical Characteristics (KA7915A) (Continued) (VI = -23V, IO = 500mA, 0°C ≤TJ ≤ +125°C, CI =2.2μF, CO =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. Parameter Symbol Conditions Min. Typ. Max.
