ELECTRICAL CHARACTERISTICS OF L7812 (refer to the test circuits, TJ= -55 to 150°C, VI= 19V,
IO=500mA,C
I=0.33µF,C
O= 0.1 µF unless otherwise specified).
(*) Load and line regulation are specified at constant junction temperature. Changes in VOdue to heating effects must be taken into account
separately. Pulse testing with low duty cycle is used.
