ETC LM4040AIX3-3.0

19-1787; Rev 0; 8/00
Improved Precision Micropower Shunt Voltage
Reference with Multiple Reverse Breakdown Voltages
Features
♦ Ultra-Small 3-Pin SC70 Package
Laser-trimmed resistors ensure precise initial accuracy.
With a 100ppm/°C temperature coefficient, the device
is offered in four grades of initial accuracy ranging from
0.1% to 1%. The LM4040 has a 60µA to 15mA shunt
current capability with low dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a
wide range of operating temperatures and currents.
♦ Low 28µVRMS Output Noise (10Hz to 10kHz)
♦ 0.1% max Initial Accuracy
♦ 100ppm/°C max Temperature Coefficient
Guaranteed over -40°C to +85°C Temperature
Range
♦ Wide Operating Current Range: 60µA to 15mA
♦ 2.048V, 2.500V, 3.000V, 4.096V, and 5.000V Fixed
Reverse Breakdown Voltage
♦ No Output Capacitors Required
♦ Tolerates Capacitive Loads
The LM4040 does not require an external stabilizing
capacitor while ensuring stability with any capacitive
load.
For a 1.225V output version, refer to the LM4041 data
sheet.

LM4040
General Description
The LM4040 is a precision two-terminal shunt mode,
bandgap voltage reference available in fixed reverse
breakdown voltages of 2.048V, 2.500V, 3.000V, 4.096V,
and 5.000V. Ideal for space-critical applications, the
LM4040 is offered in the subminiature 3-pin SC70 surface-mount package (1.8mm ✕ 1.8mm), 50% smaller
than comparable devices in SOT23 surface-mount
packages (SOT23 versions are also available).

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: All devices are 100% production tested at +25°C and are guaranteed by design for TA = TMIN to TMAX, as specified.
Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse
Breakdown Voltage Tolerance ±[(∆VR / ∆T)(max∆T)(VR)], where ∆VR / ∆T is the VR temperature coefficient, max∆T is the
maximum difference in temperature from the reference point of +25°C to TMIN or TMAX, and VR is the reverse breakdown
voltage. The total overtemperature tolerance for the different grades in the temperature range where max∆T = +65°C is
shown below:
A grade: ±0.75% = ±0.1% ±100 ppm/°C ✕ 65°C
B grade: ±0.85% = ±0.2% ±100 ppm/°C ✕ 65°C
C grade: ±1.15% = ±0.5% ±100 ppm/°C ✕ 65°C
D grade: ±1.98% = ±1.0% ±150 ppm/°C ✕ 65°C
Note 3: Guaranteed by design.

Detailed Description
The LM4040 shunt references use the bandgap principle to produce a stable, accurate voltage. The device
behaves similarly to an ideal zener diode; a fixed voltage is maintained across its output terminals when
biased with 60µA to 15mA of reverse current. The
LM4040 behaves similarly to a silicon diode when
biased with forward currents up 10mA.
Figure 3 shows a typical operating circuit. The LM4040
is ideal for providing a stable reference from a highvoltage power supply.

Applications Information
The LM4040’s internal pass transistor is used to maintain a constant output voltage (VSHUNT) by sinking the
necessary amount of current across a source resistor.
The source resistance (RS) is determined from the load
current (ILOAD) range, supply voltage (VS) variations,
VSHUNT, and desired quiescent current.
Choose the value of RS when VS is at a minimum and
ILOAD is at a maximum. Maintain a minimum ISHUNT of
60µA at all times. The RS value should be large enough
to keep ISHUNT less than 15mA for proper regulation
when VS is maximum and ILOAD is at a minimum. To
prevent damage to the device, ISHUNT should never
exceed 20mA.
Therefore, the value of RS is bounded by the following
equation:
[VS(MIN) - VR ] / [60µA + ILOAD(MAX)] > RS >
[VS(MAX) - VR ] / [20mA + ILOAD(MIN)]
Choosing a larger resistance minimizes the total power
dissipation in the circuit by reducing the shunt current
(PD(TOTAL) = VS ✕ ISHUNT). Provide a safety margin to
incorporate the worst-case tolerance of the resistor
used. Ensure that the resistor’s power rating is adequate, using the following general power equation:
PDR = ISHUNT ✕ (VS(MAX) - VSHUNT)

Output Capacitance
The LM4040 does not require an external capacitor for
frequency stability and is stable for any output capacitance.
Temperature Performance
The LM4040 typically exhibits an output voltage temperature coefficient within ±15ppm/°C. The polarity of
the temperature coefficient may be different from one
device to another; some may have positive coefficients,
and others may have negative coefficients.
