Electrical Characteristics (KA7905A) (Continued)

(VI = -10V, 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.
