Table 17: Electrical Characteristics Of L7809C (refer to the test circuits, TJ = 0 to 125°C, VI = 15V,

IO = 500 mA, CI = 0.33 µF, CO = 0.1 µF unless otherwise specified).

(*) 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 cycle is used.

Table 18: Electrical Characteristics Of L7810C (refer to the test circuits, TJ = 0 to 125°C, VI = 16V,

IO = 500 mA, CI = 0.33 µF, CO = 0.1 µF unless otherwise specified).

(*) 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 cycle is used.
