LM4040Q
AUTOMOTIVE GRADE PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES
Description
The LM4040Q is a family of bandgap circuits designed to achieve
precision micro-power voltage references of 2.5V, 3.0V and 5.0V. The
devices are available in 0.2% B-grade, 0.5% C-grade and 1%
D-grade initial tolerances.
They are available in small outline SOT23 surface mount package
which is ideal for applications where space is at a premium. Excellent
performance is maintained over the 60µA to 15mA operating current
range with a typical temperature coefficient of only 20ppm/°C. The
device has been designed to be highly tolerant of capacitive loads
therefore maintaining excellent stability.
This device offers a pin for pin compatible alternative to the industry
standard LM4040 voltage reference for automotive applications.
The LM4040Q has been qualified to AEC-Q100 Grade 1 and is
Automotive Grade supporting PPAPs

Notes:
1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS) & 2011/65/EU (RoHS 2) compliant.
2. See http://www.diodes.com/quality/lead_free.html for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free,
"Green" and Lead-free.
3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl)
and <1000ppm antimony compounds.
4. Automotive products are AEC-Q100 qualified and are PPAP capable. Automotive, AEC-Q100 and standard products are electrically and thermally
the same, except where specified. For more information, please refer to http://www.diodes.com/quality/product_compliance_definitions/.
