Notes
1. Guaranteed by design, not tested.
2. Load fault is a short circuit (<50 mΩ). Recovery is into a resistive load.
3. Load step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
4. Input step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
