LM4040
PRECISION MICROPOWER SHUNT VOLTAGE REFERENCES
Description
The LM4040 is a family of bandgap circuits designed to achieve
precision micro-power voltage references of 2.5V, 3.0V, 3.3V, 4.096V,
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 packages,
which are 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 is
designed to be highly tolerant of capacitive
loads, which maintains excellent stability.
This device
offers a pin for pin compatible alternative to the LM4040
voltage reference.

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.)
Unless otherwise stated voltages specified are relative to the Anode pin.

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.
Figure 1
RS determines the current that flows through the load (IL) and the LM4040 (IR). Because load current and supply voltage
can 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 15mA.
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
The LM4040 device in the SOT23 package has the die attached to pin 3, which results in an electrical contact between
pin 2 and pin 3. Therefore, pin 3 of the SOT23 package must be left floating or connected to pin 2.
