The output of the regulator. A minimum of 10uF capacitor must be connected from this pin to

ground to insure stability.

Vin

3

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

tage does not sag below the minimum dropout voltage during the load

transient response .This pin must always be 1.5V higher than Vout in order for the device to

V higher than Vout in order for the device to

regulate properly.

Note 1: See thermal regulation specifications for changes in output voltage due to heating effects. Line and load regulation are measured

at a constant junction Temperature by low duty cycle pulse testing .Load regulation is measured at the output lead =1/18” from the

package.

Note 2: Line and load regulation are guaranteed up to the maximum power dissipation of 15W. Power dissipation is determined by the

difference between input and output and the output current .Guaranteed maximum power dissipation will not be available over the

full input/output range.
