Electrical Characteristics
Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured
Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the

The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to
ground to insure stability.
The input pin of regulator .Typically a large storage capacitor is connected from this pin to ground
to insure that the input voltage does not sag below the min. dropout voltage during the load
transient response .This pin must always be 1.5V higher than Vout in order for the device to
regulate properly.
