Note:

“Absolute maximum rating” indicated limits beyond which damage to the device may occur. Operating ratings

indicate conditions for which the device is functional, but do not guarantee specific performance limits.

Notes:

2. Pmax: CS package=0.5W, CT package=0.625W,

3. Load and line regulation are specified at constant junction temperature. Changes in output voltage due to heating

effects must be taken into account separately. Pulse testing with low duty cycle is used.

4. Selected devices with tightened tolerance reference voltage available.

5. Since Long-Term Stability cannot be measured on each device before shipment, this specification is an engineering

estimate of average stability from lot to lot.
