AUTOMOTIVE GRADE PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES
Description
Pin Assignments
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.
LM4040 F (SOT23)
3
Cathode
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

Caution:
Stresses greater than the 'Absolute Maximum Ratings' specified above, may cause permanent damage to the device. These are stress ratings only;
functional operation of the device at conditions between maximum recommended operating conditions and absolute maximum ratings is not implied.
Device reliability may be affected by exposure to absolute maximum rating conditions for extended periods of time.
Semiconductor devices are ESD sensitive and may be damaged by exposure to ESD events. Suitable ESD precautions should be taken when
handling and transporting these devices.)

LM4040Q
Application Information
In a conventional shunt regulator application (Figure 1), an external series resistor (RS) is connected between the supply voltage, VS, and the
LM4040.
RS determines the current that flows through the load (IL) and the LM4040 (IR). Since load current and supply voltage may
vary, RS should be small enough to supply at least the minimum acceptable IR to the LM4040 even when the supply voltage
is at its minimum and the load current is at its maximum value. When the supply voltage is at its maximum and IL is at its
VS
minimum, RS should be large enough so that the current flowing through the LM4040 is less than 15 mA.
IR +
IL
RS is determined by the supply voltage, (VS), the load and operating current, (IL and IR), and the LM4040’s reverse
breakdown voltage, VR.

Printed circuit board layout considerations
LM4040Qs in the SOT23 package have the die attached to pin 1, which results in an electrical contact between pin 2 and pin
3. Therefore, pin 1 of the SOT-23 package must be left floating or connected to pin 2.
