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

voltage due to temperature changes must be taken into account separately.

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

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

6. Minimum load current is defined as the minimum output current required to maintain regulation. The reference resistor in the output divider

is usually sized to fulfill the minimum load current requirement.

7. Guaranteed by design, not 100% functionally tested in production.

8. Guaranteed by design, not 100% parametrically tested in production. However, every part is subject to functional testing for thermal

shutdown.
