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.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance
characteristics may degrade when the device is not operated under the listed test conditions.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by T
JMAX
(maximum junction temperature), θ
J-A
(junction to ambient thermal resistance) and T
A
(ambient temperature). The maximum power
dissipation at any temperature is: PDiss

J-A
up to the value listed in the Absolute Maximum Ratings. The θ
J-A
for the
SO-8 package is 160°C/W.
(4) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF
capacitor discharged directly into each pin.

(1) For proper operation, a 1μF capacitor is required between the output pin and the GND pin of the device. (See Application Hints for
details)
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
(3) Typical numbers are at 25°C and represent the most likely parametric norm.
(4) High temperature and mechanical stress associated with PCB assembly can have significant impact on the initial accuracy of the
LM4140 and may create significant shifts in V
REF
. See Application Hints section regarding accuracy and PCB layout consideration.
