Note:
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. Line load regulation guaranteed maximum power dissipation 15W. Power dissipation determined difference between input output differential output current. Guaranteed maximum power dissipation will available over full input/output range. VOUT 100mV Quiescent current defined minimum output current required maintaining regulation. input/output differential device guaranteed regulate output current greater than 10mA. Test condition SOT223-3L: TA=27 flow, copper, 5mmX5mm pad. Test condition TO252-3L: TA=27 flow, copper, 5mmX5mm pad.
