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

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

minimum, RS should be large enough so that the current flowing through the LM4040 is less than 15 mA.

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.
