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 3: The maximum power dissipation is a function of T j(MAX) , ΘjA and T A . The maximu allowable power dissipation at any ambient temperature is P D=(T j(MAX) – T A)ΘjA . NOTES 4: Typical Values represent the most likely parametric norm NOTES 5: All limits are guaranteed by testing or statistical analysis NOTES 6: IFULL LOAD is defind in the current limit curves . The I FULL LOAD curve defines the current limit as function 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
