These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. Power Dissipation (Note 2) Internally Limited Block Diagram 2011, February, Rev. 01 IL1085-xx Electrical Characteristics Typicals and limits appearing in normal type apply for Tj= +25°C. Limits appearing in Boldface type apply over the entire junction temperature range for operation. 2011, February, Rev. 01 IL1085-xx Electrical Characteristics Typicals and limits appearing in normal type apply for Tj= +25°C. Limits appearing in Boldface type apply over the entire junction temperature range for operation. NOTES 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Rating indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. 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 Tj(MAX), ΘjA and TA . The maximum allowable power dissipation at any ambient temperature is PD=(Tj(MAX) – TA)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 IFULL LOAD curve defines the current limit as a function of inputto-output voltage . 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. 2011, February, Rev. 01 IL1085-xx Typical Applications Adjusting Output Voltage Regulator with Reference 2011, February, Rev. 01 IL1085-xx 2011, February, Rev. 01 IL1085-xx 2011, February, Rev. 01
