PERFORMANCE

Notes

1. Guaranteed by characterization test and/or analysis. Not a production test.

2. A minimum load of 20% is recommended.

3. Short circuit measured with 1% 10 milliohm resistive load.

4. Indefinite short circuit protection not guaranteed above 125°C.

5. Recovery and startup times are measured from application of the transient or

6. Step load transition time 10 µs ±1 µs.

7. Step line transition time 100 µs ±20 µs.

8. Tested on release from inhibit.
