†
All characteristics are measured with a 0.33-µF capacitor across the input and a 0.1-µF capacitor across the output. 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.
‡
This specification applies only for dc power dissipation permitted by absolute maximum ratings.
