Notes:
1. T
2. Pmax is internally limited
3. Load and line regulation are specified at constant junction temperature. Changes in V
4. Cadj, 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
6. Power dissipation within an IC voltage regulator produces a temperature gradient on the die, affecting individual IC
