* 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 0.33µF capacitor across the input and a 0.1µF capacitor across the output.
** This specification applies only for dc power dissipation permitted by absolute maximum ratings.
