Note 1. Absolute maximum ratings indicate limits beyond which damage to the device may occur. Operating

Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific

performance limits. The guaranteed specifications apply only for the test conditions listed.

operating temperature range are assured by design, characterization and correlation with Statistical

Quality Controls (SQC).

3. Load regulation is measured at constant junction temperature, using pulse testing with a short ON time.

The devices are guaranteed up to the maximum power dissipation. Power dissipation is determined by the

input/output differential voltage and the output current. Guaranteed maximum power dissipation will not

be available over the full input/output range. The maximum allowable power dissipation at any ambient
