Note1: thermal regulation specifications 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. Note2: Line load regulation guaranteed maximum power dissipation 15W. Power dissipation determined input/output differential output current. Guaranteed maximum power dissipation will available over full input/output range. Note3: Quiescent current defined minimum output current required maintain regulation. input/output differential device guaranteed regulate output current greater than 10mA.
