Electrical Characteristics: 25°C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
Notes
1. Indefinite short circuit protection not guaranteed above 100°C (case)
2. Recovery time is measured from application of the transient to point at
which Vout is within regulation.
3. Input step transition time >10s.
4. Input step transition time <100s.
