Notes:1.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.

2.CAdj, when used, is connected between the adjustment pin and ground.

3.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.

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.
