2 / 15 page LM3480 SNVS011E – JUNE 1999 – REVISED MARCH 2013 www.ti.com 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) Input Voltage (IN to GND) 35V Power Dissipation (3) 333mW Junction Temp. (3) +150°C Ambient Storage Temp. −65 to +150°C Soldering Time, Temp. (4) Wave 4 sec., 260°C Infrared 10 sec., 240°C Vapor Phase 75 sec., 219°C ESD (5) 2kV (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics. (2) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications. (3) The Absolute Maximum power dissipation depends on the ambient temperature and can be calculated using P = (TJ - TA)/θJA where TJ is the junction temperature, TA is the ambient temperature, and θJA is the junction-to-ambient thermal resistance. The 333 mW rating results from substituting the Absolute Maximum junction temperature, 150°C, for TJ , 50°C for TA, and 300°C/W for θJA. More power can be safely dissipated at lower ambient temperatures. Less power can be safely dissipated at higher ambient temperatures. The Absolute Maximum power dissipation can be increased by 3.33 mW for each °C below 50°C ambient. It must be derated by 3.33 mW for each °C above 50°C ambient. A θJA of 300°C/W represents the worst-case condition of no heat sinking of the 3-lead plastic SOT-23 package. Heat sinking enables the safe dissipation of more power. The LM3480 actively limits its junction temperature to about 150°C. (4) Times shown are dwell times. Temperatures shown are dwell temperatures. For detailed information on soldering plastic small-outline packages, refer to the Packaging Databook . (5) For testing purposes, ESD was applied using the human-body model, a 100 pF capacitor discharged through a 1.5 k Ω resistor. Operating Ratings (1) Max. Input Voltage (IN to GND) 30V Junction Temp. (TJ) −40 to +125°C Max. Power Dissipation (2) 250mW (1) Absolute Maximum Ratings are limits beyond which damage to the device may occur. Operating Ratings are conditions under which operation of the device is ensured. Operating Ratings do not imply ensured performance limits. For ensured performance limits and associated test conditions, see the Electrical Characteristics. (2) As with the Absolute Maximum power dissipation, the maximum power dissipation for operation depends on the ambient temperature. The 250 mW rating appearing under Operating Ratings results from substituting the maximum junction temperature for operation, 125°C, for TJ, 50°C for TA, and 300°C/W for θJA in P = (TJ - TA)/θJA. More power can be dissipated at lower ambient temperatures. Less power can be dissipated at higher ambient temperatures. The maximum power dissipation for operation appearing under Operating Ratings can be increased by 3.33 mW for each °C below 50°C ambient. It must be derated by 3.33 mW for each °C above 50°C ambient. A θJA of 300°C/W represents the worst-case condition of no heat sinking of the 3-lead plastic SOT-23 package. Heat sinking enables the dissipation of more power during operation. Electrical Characteristics LM3480-3.3, LM3480-5.0 Typicals and limits appearing in normal type apply for TA = TJ = 25°C. Limits appearing in boldface type apply over the entire junction temperature range for operation, −40 to +125°C.

Typicals are not ensured. (2) All limits are ensured. All electrical characteristics having room-temperature limits are tested during production with TA = TJ = 25°C. All hot and cold limits are ensured by correlating the electrical characteristics to process and temperature variations and applying statistical process control. (3) All voltages except dropout are with respect to the voltage at the GND pin. 2 Submit Documentation Feedback Copyright © 1999–2013, Texas Instruments Incorporated Product Folder Links: LM3480 |
