† Notice: Stresses above those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
This is a stress rating only and functional operation of the device at those or any other conditions above those indicated
in the operational sections of this specification is not intended. Exposure to maximum rating conditions for extended
periods may affect device reliability.
‡ Notice: The device is not guaranteed to function outside its operating ratings.
Note 1: The maximum power dissipation must be derated at elevated temperatures and is dictated by T
JMAX
(max-
imum junction temperature), 
JA
(junction-to-ambient thermal resistance), and T
A
(ambient temperature).
The maximum allowable power dissipation at any temperature is P
DMAX
= (T
JMAX
– T
A
)/ 
JA
or the number
given in the Absolute Maximum Ratings, whichever is lower. For the LM4040 and LM4041, T
JMAX
= +125°C
and the typical thermal resistance, when board-mounted, is +326°C/W for the SOT-23 package.
2: Devices are ESD sensitive. Handling precautions are recommended. Human body model, 1.5 k in series
with 100 pF. The machine model is a 200 pF capacitor discharged directly into each pin.
