Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. All characteristics are
measured with a 0.33-

Pulse-testing techniques maintain TJ as close to TA as possible. Thermal effects must be taken into account separately. All characteristics are
measured with a 0.33-
F capacitor across the input and a 0.1-F capacitor across the output. Full range for the A78L05AC is TJ = 0°C to 125°C,
and full range for the
A78L05AI is TJ = 40°C to 125°C.
