(1) All characteristics are measured with a capacitor across the input of 0.22F and a capacitor across the output of 0.1F. Although power dissipation is internally limited, theses specifications are applicable to maximum power dissipation PMAX = 20W, IMAX = 1.0A, TJ = 25C (2) Regulation is measured at constant junction temperature, using pulse testing at a low duty cycle. Changes in output voltage due to heating effects must be taken into account separately. (3) By design, not a production test.
