See thermal regulation specification for changes in output voltage due to heating effects. 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. 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. 3. Quiescent current is defined as the minimum output current required to maintain the regulation. 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. OUT 2 Version: H1607
