† _{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.}
