Line and load regulation are measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18 from the package. Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the input / output voltage difference and the output current. Guaranteed maximum power dissipation will not be available over the full input / output voltage range. Note 3: Quiescent current is defined as the minimum output current required to maintain the regulation. Note 4: The Output Capacitor does not have a theoretical upper limit and increasing its value will increase stability C =100uF or more is typical for high current regulator design.
