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
V_IN = 15V, I_O = 0mA, and T_J = 25°C.
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
150°C.
Note 9: Guaranteed but not tested.
