Note 3. Load and line regulation are specified at constant junction temperature. Changes in V
O
due
to heating effects must be taken into account separately. Pulse testing with low duty cycle
is used.
Note 4. C
Adj
, 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.
