* 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 0.1 µF

capacitor across the output.

** This specification applies only for dc power dissipation permitted by absolute maximum ratings.
