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
change in condition to the point at which V_OUT is within 1% of final value. C_L = 0.
6. Step load transition time 10 µs ±1 µs.
7. Step line transition time 100 µs ±20 µs.
8. Tested on release from inhibit.
