2. Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in output

voltage due to thermal gradients or temperature changes must be taken into account seperately.

3. Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4” from the bottom of the package.

4. Dropout voltage is a measurement of the minimum input/output differential at full load.
