Note 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.
Note 4. CAdj, when used, is connected between the adjustment pin and GND.
Note 5. Since Long–Term Stability cannot be measured on each device before shipment, this speci-
fication is an engineering estimate of average stability from lot to lot.
