4 / 31 page LP2950 LP2951 SLVS582H – APRIL 2006 – REVISED MARCH 2012 www.ti.com ABSOLUTE MAXIMUM RATINGS (1) over operating free-air temperature range (unless otherwise noted) VIN Continuous input voltage range –0.3 V to 30 V VSHDN SHUTDOWN input voltage range –1.5 V to 30 V ERROR comparator output voltage range(2) –1.5 V to 30 V VFDBK FEEDBACK input voltage range(2) (3) –1.5 V to 30 V D package(5) 97°C/W DRG package(6) 52.44°C/W θJA Package thermal impedance(4) LP package(5) 140°C/W P package(5) 84.6°C/W TJ Operating virtual-junction temperature 150°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) May exceed input supply voltage (3) If load is returned to a negative power supply, the output must be diode clamped to GND. (4) 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. (5) The package thermal impedance is calculated in accordance with JESD 51-7. (6) The package thermal impedance is calculated in accordance with JESD 51-5. RECOMMENDED OPERATING CONDITIONS MIN MAX UNIT VIN Supply input voltage (1) 30 V TJ Operating virtual junction temperature –40 125 °C (1) Minimum VIN is the greater of: (a) 2 V (25°C), 2.3 V (over temperature), or (b) VOUT(MAX) + Dropout (Max) at rated IL 4 Submit Documentation Feedback Copyright © 2006–2012, Texas Instruments Incorporated Product Folder Link(s): LP2950 LP2951 |
