Note1: 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.

Note2: Line and load regulation are guaranteed up to the maximum power dissipation of

5W. Power dissipation is determined by the difference between

input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full input/output range.

Note3: Quiescent current is defined as the minimum output current required in maintaining regulation. At

6V input/output differential the

device is guaranteed to regulate if the output current is greater than 10mA.
