Notes
1. Specified at 50% of full load.
2. Lin = 2 μH
3. Max. duration of short circuit: 25°C– 90 seconds; 125°C – 30 seconds.
4. Load fault is a short circuit (<50 mohms). Recovery into resistive full load.
5. Input step transition
≥
10 μs.Recovery is time to settle to within 1% of Vout
final value.
