LM4040 Improved Precision Micropower Shunt Voltage Reference with Multiple Reverse Breakdown Voltages General Description The LM4040 is a precision, two-terminal shunt mode, bandgap voltage reference available in fixed reversebreakdown voltages of 2.048V, 2.500V, 3.000V, 3.3V, 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 x 1.8mm), 50% smaller than comparable devices in SOT23 surface-mount packages (SOT23 versions are also available). 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 60A to 15mA shunt current capability with low dynamic impedance, ensuring stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents. The LM4040 does not require an external stabilizing capacitor while ensuring stability with any capacitive load. The LM4040 is guaranteed over the temperature range of -40C to +125C. For a 1.225V output version, refer to the LM4041 data sheet.

Note 2: The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room-temperature Reverse Breakdown Voltage Tolerance [(VR/T)(maxT)(VR)], where VR/T is the VR temperature coefficient, maxT is the maximum difference in temperature from the reference point of +25C to TMIN or TMAX, and VR is the reverse breakdown voltage. The total overtemperature tolerance for the different grades in the temperature range where maxT = +65C is shown below: A grade: 0.75% = 0.1% 100ppm/C x 65C B grade: 0.85% = 0.2% 100ppm/C x 65C C grade: 1.15% = 0.5% 100ppm/C x 65C D grade: 1.98% = 1.0% 150ppm/C x 65C The total over-temperature tolerance for the different grades in the extended temperature range where max T = +100C is shown below: A grade: 1.1% = 0.1% 100ppm/C x 100C B grade: 1.2% = 0.2% 100ppm/C x 100C C grade: 1.5% = 0.5% 100ppm/C x 100C D grade: 2.5% = 1.0% 150ppm/C x 100C Therefore, as an example, the A-grade LM4040-2.5 has an over-temperature reverse breakdown voltage tolerance of 2.5V x 0.75% = 19mV.

The device behaves similarly to an ideal zener diode; a fixed voltage is maintained across its output terminals when biased with 60A 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. VS ISHUNT + ILOAD RS ILOAD VR ISHUNT LM4040 Applications Information The device'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 60A 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 ] / [60A + 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 x 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 x (VS(MAX) - VSHUNT) Output Capacitance Figure 3. Typical Operating Circuit 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. High-Temperature Operation The maximum junction temperature of the LM4040 is +150C. The maximum operating temperature for the LM4040_E_ is +125C. At a maximum load current of 15mA and a maximum output voltage of 5V, the part will dissipate 75mW of power. The power dissipation limits of the 3-pin SC70 call for a derating value of 2.17mW/C above +70C and, therefore, for 75mW of power dissipation, the part will selfheat to 35.56C above ambient temperature. If the ambient temperature is +125C, the part operates at 159.56C, thereby exceeding the maximum junction temperature value of +150C. For high-temperature operation, care must be taken to ensure the combination of ambient temperature, output power dissipation and package thermal resistance does not conspire to raise the device temperature beyond that listed in the Absolute Maximum Ratings. Either reduce the output load current or the ambient temperature to keep the part within the limits. The device does not require an external capacitor for frequency stability and is stable for any output capacitance. www.maximintegrated.com Maxim Integrated 12 LM4040 Improved Precision Micropower Shunt Voltage Reference with Multiple Reverse Breakdown Voltages Ordering Information OUTPUT VOLTAGE (V) INITIAL ACCURACY (%) TEMPCO (ppm/C) LM4040AIM3-2.1+T 2.048 0.1 100 LM4040AIX3-2.1+T 2.048 0.1 100 LM4040BIM3-2.1+T 2.048 0.2 LM4040BIX3-2.1+T 2.048 0.2 LM4040CIM3-2.1+T 2.048 LM4040CIX3-2.1+T LM4040DIM3-2.1+T PIN-PACKAGE TOP MARK -40C to +85C 3 SOT23 FZEF -40C to +85C 3 SC70 ABJ 100 -40C to +85C 3 SOT23 FZEG 100 -40C to +85C 3 SC70 ABK 0.5 100 -40C to +85C 3 SOT23 FZEH 2.048 0.5 100 -40C to +85C 3 SC70 ABL 2.048 1.0 150 -40C to +85C 3 SOT23 FZEI LM4040DIX3-2.1+T 2.048 1.0 150 -40C to +85C 3 SC70 ABM LM4040AEM3-2.1+T 2.048 0.1 100 -40C to +125C 3 SOT23 FZNG LM4040AEX3-2.1+T 2.048 0.1 100 -40C to +125C 3 SC70 ALF LM4040BEM3-2.1-T 2.048 0.2 100 -40C to +125C 3 SOT23 FZNH LM4040BEX3-2.1-T 2.048 0.2 100 -40C to +125C 3 SC70 ALG LM4040CEM3-2.1-T 2.048 0.5 100 -40C to +125C 3 SOT23 FZNI LM4040CEX3-2.1+T 2.048 0.5 100 -40C to +125C 3 SC70 ALH LM4040DEM3-2.1+T 2.048 1.0 150 -40C to +125C 3 SOT23 FZNJ LM4040DEX3-2.1+T 2.048 1.0 150 -40C to +125C 3 SC70 ALI LM4040AIM3-2.5+T 2.500 0.1 100 -40C to +85C 3 SOT23 FZEJ LM4040AIX3-2.5+T 2.500 0.1 100 -40C to +85C 3 SC70 ABN LM4040BIM3-2.5+T 2.500 0.2 100 -40C to +85C 3 SOT23 FZEK LM4040BIX3-2.5+T 2.500 0.2 100 -40C to +85C 3 SC70 ABO LM4040BIM3-2.5/V+T 2.500 0.2 100 -40C to +125C 3 SOT23 FZWL LM4040CIM3-2.5+T 2.500 0.5 100 -40C to +85C 3 SOT23 FZEL LM4040CIX3-2.5+T 2.500 0.5 100 -40C to +85C 3 SC70 ABP LM4040DIM3-2.5+T 2.500 1.0 150 -40C to +85C 3 SOT23 FZEM LM4040DIX3-2.5+T 2.500 1.0 150 -40C to +85C 3 SC70 ABQ LM4040AEM3-2.5+T 2.500 0.1 100 -40C to +125C 3 SOT23 FZNK LM4040AEX3-2.5+T 2.500 0.1 100 -40C to +125C 3 SC70 ALJ LM4040BEM3-2.5+T 2.500 0.2 100 -40C to +125C 3 SOT23 FZNL LM4040BEX3-2.5+T 2.500 0.2 100 -40C to +125C 3 SC70 ALK LM4040CEM3-2.5+T 2.500 0.5 100 -40C to +125C 3 SOT23 FZNM LM4040CEM3-2.5/V+T 2.500 0.5 100 -40C to +125C 3 SOT23 FZVZ LM4040CEX3-2.5+T 2.500 0.5 100 -40C to +125C 3 SC70 ALL LM4040DEM3-2.5+T 2.500 1.0 150 -40C to +125C 3 SOT23 FZNN LM4040DEX3-2.5+T 2.500 1.0 150 -40C to +125C 3 SC70 ALM PART TEMP RANGE +Denotes a lead(Pb)-free/RoHS-compliant package.
