Notes: 1. TLOW to THIGH = 0

oC to +125oC, Pmax is internally limited

2. 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.

3. Cadj, when used, is connected between the adjustment pin and ground. 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 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.
