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 3W. Power dissipation is determined by the difference in input and output and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range. LM1117M3 series CYStek Product Specification CYStech Electronics Corp. Spec.
