Note : 1.See thermal regulation specifications 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 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.
