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 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 voltage range.
3. Dropout voltage is specified over the full output current range of the device.
4. Minimum load current is defined as the minimum output current required to maintain regulation. At 25V input-output
differential the device is guaranteed to regulate if the output current is greater than 10mA.
