Improved Precision Micropower Shunt Voltage Reference with Multiple Reverse Breakdown Voltages LM4040 Pin Description PIN NAME FUNCTION 1 + Positive Terminal of the Shunt Reference 2 − Negative Terminal of the Shunt Reference 3 N.C. No connection. Leave this pin unconnected or connected to Pin 2. 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. VS ISHUNT + ILOAD RS 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 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) 10 LM4040 Figure 3. Typical Operating Circuit 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.
