Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Unless otherwise indicated, these specifications apply for

Note 3: Line and load regulation is measured using a low duty cycle pulse,

causing little change in the junction temperature. Effects due to thermal

gradients and device heating must be taken into account separately.

Note 4: When the enable pin is at a low logic level, current flows out of the

enable pin.

Note 5: Pulse length for this measurement is 20ms.

Note 6: Input voltage is reduced until output drops by 100mV from its

initial value.

Note 7: See “Guaranteed Load Current” graph.

Note 8: Continuous shorts on the auxiliary output are not allowed unless

adequate heat sinking is used to maintain junction temperature below
