NOTES 1: Rating indicate conditions for which the device is intended to be functional, but specific performance is not Guaranteeed.

For guaranteed specifications and the test conditions, see the Electrical Characteristics.

NOTES 2: Power Dissipation is kept in a safe range by current limiting circuitry. Refer to Overload Recovery

in Application Notes.

NOTES 4: Typical Values represent the most likely parametric norm

NOTES 5: All limits are guaranteed by testing or statistical analysis

NOTES 7: Load and Line regulation are measured at constant junction temperature , and are guaranteed up to the maximum power

dissipation of 30W.Power dissipation is determined by the input/output differential and the output current. Guaranteed maximum power

dissipation will not be available over the full input/output range.

NOTES 8: Dropout voltage is specified over the full output current range of the device
