Note thermal regulation specification changes output voltage heating effects. Line load regulation measured constant junction temperature duty cycle pulse testing. Load regulation measured output lead 1/18" from package. Note Line load regulation guaranteed maximum power dissipation 15W. Power dissipation determined input output voltage difference output current. Guaranteed maximum power dissipation will available over full input output voltage range. Note Quiescent current defined minimum output current required maintain regulation.
