table 7: electrical characteriSticS: -55°c to +125°c caSe, 28 vin, 100% loaD, Free run, unleSS otherWiSe SpeciFieD.

Notes

1. Guaranteed by characterization test and/or analysis. Not a production test.

2. Operation is limited below 16 V (see Figure 22 on page 10).

3. Tested with 6800 pF ceramic bypass capacitor connected externally from

input common to case.

4. Short circuit protection not guaranteed above 125°C case temperature.

5. Recovery time is measured from application of the transient to the point

at which VOUT is within 1% of final value.

6. Tested on release from inhibit.
