Notes
1. Guaranteed by design, not tested.
2. Up to 7.5 watts is available from either output.
3. Load fault is a short circuit (<50 mΩ). Recovery is into a resistive load.
4. Load step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
5. Input step transition ≥ 10 μs. Recovery = time to settle to within 1% of Vout final value.
