The ● denotes the specifications which apply over the full operating temperature range.

(1)

All characteristics are measured with a capacitor across the input of 0.22µF and a capacitor across the output of 0.1µF. Although power

dissipation is internally limited, theses specifications are applicable to maximum power dissipation PMAX = 2W, IMAX = 0.5A, TJ = 25°C

(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.
