Notes
1. MSA2860S specifications are at 25°Tc only, contact your Interpoint
representative for more information on over temperature specs.
2. Line regulation for /ES and non /ES 2805S models at 16 to 17 VIN and 110
°C to 125°C (case) is 5% (max).
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 VOUT at final value.
5. Transition time >10µs.
