SLVS719E – JUNE 2008 – REVISED AUGUST 2009 ABSOLUTE MAXIMUM RATINGS (1) over operating free-air temperature range (unless otherwise noted) IN –20 V to 20 V OUT –20 V to 20 V Input-to-output differential(2) –20 V to 20 V VIN Input voltage range SENSE –20 V to 20 V ADJ –7 V to 7 V SHDN –20 V to 20 V tshort Output short-circuit duration Indefinite Tlead Maximum lead temperature 10-second soldering time 300°C TJ Operating virtual-junction temperature range –40°C to 125°C Tstg Storage temperature range –65°C to 150°C (1) Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device. 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. (2) Absolute maximum input-to-output differential voltage cannot be achieved with all combinations of rated IN pin and OUT pin voltages. With the IN pin at 20 V, the OUT pin may not be pulled below 0 V. The total measured voltage from IN to OUT cannot exceed ±20 V. PACKAGE THERMAL DATA (1) PACKAGE BOARD θJA θJC θJP (2) SOT-223 (DCY) High K, JESD 51-5 48.3°C/W 30.6°C/W — TO-223 (DCQ) High K, JESD 51-5 53°C/W 15°C/W — TO-263 (KTT) High K, JESD 51-5 26.5°C/W 24.1°C/W 0.38°C/W (1) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability. (2) For packages with exposed thermal pads, such as QFN, PowerPAD™, and PowerFLEX™, θJP is defined as the thermal resistance between the die junction and the bottom of the exposed pad.
