3 / 24 page N/C 4 5 3 2 1 VIN GND VEN VOUT LP3990 www.ti.com SNVS251I – MAY 2004 – REVISED MAY 2013 SOT-23 Package See Package Number DBV These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates. Absolute Maximum Ratings (1) (2) (3) Input Voltage -0.3 to 6.5V Output Voltage -0.3 to (VIN + 0.3V) with 6.5V (max) Enable Input Voltage -0.3 to (VIN + 0.3V) with 6.5V (max) Junction Temperature 150°C Lead/Pad Temp.(4) WQFN/SOT-23 235°C DSBGA 260°C Storage Temperature -65 to 150°C Continuous Power Dissipation Internally Limited(5) ESD(6) Human Body Model 2KV Machine Model 200V (1) All Voltages are with respect to the potential at the GND pin. (2) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. (3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (4) For further information on these packages please refer to the following Application Notes; AN1112 DSBGA Package Wafer Level Chip Scale Package, AN1187 Leadless Leadframe Package. (5) Internal thermal shutdown circuitry protects the device from permanent damage. (6) The human body model is 100pF discharged through a 1.5k Ω resistor into each pin. The machine model is a 200pF capacitor discharged directly into each pin. Operating Ratings (1) Input Voltage 2V to 6V Enable Input Voltage 0 to (VIN + 0.3V) with 6.0V (max) Junction Temperature -40°C to 125°C Ambient Temperature TA Range (2) -40°C to 85°C (1) Absolute Maximum Ratings are limits beyond which damage can occur. Operating Ratings are conditions under which operation of the device is guaranteed. Operating Ratings do not imply guaranteed performance limits. For guaranteed performance limits and associated test conditions, see the Electrical Characteristics tables. (2) The maximum ambient temperature (TA(max)) is dependant on the maximum operating junction temperature (TJ(max-op) = 125°C), the maximum power dissipation of the device in the application (PD(max)), and the junction to ambient thermal resistance of the part/package in the application ( θJA), as given by the following equation: TA(max) = TJ(max-op) - (θJA × PD(max)).
