Note 1: Load regulation and output voltage are measured at a constant junction temperature by low duty cycle pulse testing. Changes in out-

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

Note 2: Specifications apply for an external Kelvin sense connection at a point on the output pin 1/4Ó from the bottom of the package.

Note 3: Dropout voltage is a measurement of the minimum input/output differential at full load.
