Notes:
1. T_LOW to T_HIGH = -20^oC to +125^oC
2. P_MAX, is internally limited
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. C_ADJ, when used, is connected between the adjustment pin and ground.
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. 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 in the effect of these temperature gradients on the output voltage and is expressed in the
percentage of output change per watt of power change in a specified time.
