ELECTRICAL CHARACTERISTICS OF L7809C
(refer to the test circuits, T
J
= -55 to 150°C, V
I
= 15V,
I
O
= 500 mA, C
I
= 0.33 μF, C
O
= 0.1 μF unless otherwise specified).
(*) Load and line regulation are specified at constant junction temperature. Changes in V
O
due to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
