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 diffe rence and the output current. Guaranteed maximum power dissipation will not be available over the fu ll input / output voltage range. Note 3: Qu iescent current is defined as the m inimum output c urrent required to main tain the regulation. TS1117S 2 -6 2005/11 rev.
