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 15W. Power dissipation is determined by the

input/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 to maintain regulation. At 12V input/output differential the

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