Pulse-testing techniques are used to maintain the junction temperature as close to the ambient temperature as possible. Thermal effects must
be taken into account separately. All characteristics are measured with a 0.33-
μ
F capacitor across the input and a 0.1-
μ
F capacitor across the
output.
This specification applies only for dc power dissipation permitted by absolute maximum ratings.
§Full range virtual junction temperature is 0

C to 125
°
C for uA78L12C, uA78L12AC, uA78L15C, and uA78L15AC.
