6 / 23 page  tAbLe 6: eLeCtriCAL CHArACteristiCs -55°C to +125°C CAse, 28 vin, 100% LoAD, Free run, unLess otHerwise sPeCiFieD. 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 VOUT is within 1% of final value. CL = 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.
