NAME (GND) FUNCTION
resistor divider from this Vout ground sets output voltage. (Ground only Fixed-Mode) output regulator. minimum 10uF capacitor must connected from this ground insure stability. input regulator. Typically large storage capacitor connected from this ground insure that input voltage does below minimum dropout voltage during load transient response. This must always 1.3V higher than Vout order device regulate properly.

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.
