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.
4. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC components on the die.
These effects can be minimized by proper integrated circuit design and layout techniques. Thermal Regulation is the effect of these
temperature gradients on the output voltage and is expressed in percentage of output change per watt of power change in a specified time.
5. C
Adj
, when used, is connected between the adjustment pin and ground.
6. Since LongTerm Stability cannot be measured on each device before shipment, this specification is an engineering estimate of average
stability from lot to lot.
