Electrical Characteristics:25C Tc, 28 VDC Vin, 100% load, free run, unless otherwise specified.
Notes
1. Tc = –55°C to +125°C
2. Operation is limited below 16V (see Figure 15).
3. Indefinite short circuit protection not guaranteed above 125°C case.
4. Recovery time is measured from application of the transient to point at which
Vout is within 1% of final value.
5. Transition time
≥ 10 s.
