Notes:

1. TLOW = -20

oC, T

HIGH = + 150

2. Pmax: CZ package=20W, CM package=3W, CP package=1.5W, CW package=0.8W,

3. Load and line regulation are specified at constant junction temperature. Changes in VO 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.

6. Cadj, when used, is connected between the adjustment pin and ground.
