Notes:

5. See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured at a constant

junction temperature by low duty cycle pulse testing. Load regulation is measured at the output lead = 1/18” from the package.

6. Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the difference

between input and output differential and the output current. Guaranteed maximum power dissipation will not be available over the full

input/output range.

7. Quiescent current is defined as the minimum output current required in maintaining regulation. At 12V input/output differential the

device is guaranteed to regulate if the output current is greater than 10mA.

8. Test condition for SOT223: Ta=27

°C, no air flow, 2 oz copper, 5mmx5mm pad.

9. Test condition for TO252: Ta=27

°C, no air flow, 2 oz copper, 5mmx5mm pad.

10. Test condition for SOT89-3L: no air flow, no heat sink.

11. Test condition for TO220-3L: with copper area of approximately 3in

2, 1 oz, no air flow.

12. Test condition for TO263-3L: with copper area of approximately 2cmX2cm, 1 oz, no air flow.
