Note 1. Power dissipation is internally limited, these specifications are applicable for power dissipations
up to 50W.
Note 2. Regulation is measured at constant junction temperature. Changes in output voltage due
to heating effects are taken into account separately by thermal regulation.
Note 3. Selected devices with tightened tolerance reference voltage.
