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 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). 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. For a 1.225V output version, refer to the LM4041 data sheet. o Ultra-Small 3-Pin SC70 Package o 0.1% max Initial Accuracy o 100ppm/C max Temperature Coefficient Guaranteed over -40C to +85C Temperature Range o Wide Operating Current Range: 60A to 15mA o Low 28VRMS Output Noise (10Hz to 10kHz) o 2.048V, 2.500V, 3.000V, 4.096V, and 5.000V Fixed Reverse Breakdown Voltage o No Output Capacitors Required o Tolerates Capacitive Loads

Note 1: All devices are 100% production tested at +25C 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)(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% 100 ppm/C 65C B grade: 0.85% = 0.2% 100 ppm/C 65C C grade: 1.15% = 0.5% 100 ppm/C 65C D grade: 1.98% = 1.0% 150 ppm/C 65C Note 3: Guaranteed by design.

LM4040
Pin Description
PIN 1 2 3 NAME + - N.C. Positive Terminal of the Shunt Reference Negative Terminal of the Shunt Reference No connection. Leave this pin unconnected or connected to Pin 2. FUNCTION
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 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.

ISHUNT + ILOAD ILOAD VR
ISHUNT
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 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 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.
