Notes:
1. See thermal regulation specifications for changes in output voltage due to heating effects. Load and line regulation are
measured at a constant junction temperature by low duty cycle pulse testing. Load regulation is measured at the output
lead » ^1/8” from the package.
2. Line and load regulation are guaranteed up to the maximum power dissipation of 30W. 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 voltage range.
3. Dropout voltage is specified over the full output current range of the device.
