The REF31xx’s small size and low power consumption (100µA typ) make it ideal for portable and battery-powered applications. The REF31xx does not require a load capacitor, but is stable with any capacitive load and can sink/source up to 10mA of output current. Unloaded, the REF31xx can be operated on supplies down to 5mV above the output voltage. All models are specified for the wide temperature range of –40°C to +125°C.

The basic bandgap topology is shown in Figure 1. Transistors Q1 and Q2 are biased such that the current density of Q1 is greater than that of Q2. The difference of the two base-emitter voltages, Vbe1 – Vbe2, has a positive temperature coefficient and is forced across resistor R1. This voltage is gained up and added to the base-emitter voltage of Q2, which has a negative temperature coefficient. The resulting output voltage is virtually independent of temperature. 100µA, and the maximum quiescent current over temperature is just 135µA. The quiescent current typically changes less than 2µA over the entire supply range, as shown in Figure 3. QUIESCENT CURRENT vs POWER SUPPLY 100.5 Quiescent Current (µA) 100.0 99.5 99.0 98.5 VBANDGAP R1 98.0 1.5 2.5 3.5 Power Supply (V) 4.5 5.5 + + Vbe1 Vbe2 – – Q1 I N Q2 FIGURE 3. Supply Current vs Supply Voltage. Supply voltages below the specified levels can cause the REF31xx to momentarily draw currents greater than the typical quiescent current. This can be prevented by using a power supply with a fast rising edge and low output impedance. FIGURE 1. Simplified Schematic of Bandgap Reference. APPLICATION INFORMATION The REF31xx does not require a load capacitor and is stable with any capacitive load. Figure 2 shows typical connections required for operation of the REF31xx. A supply bypass capacitor of 0.47µF is recommended. THERMAL HYSTERESIS Thermal hysteresis for the REF31xx is defined as the change in output voltage after operating the device at 25°C, cycling the device through the specified temperature range, and returning to 25°C. It can be expressed as:  abs VPRE – VPOST  6 VHYST =   • 10 (ppm) VNOM   VIN 1 0.47µF REF31xx 3 Where: VHYST = Thermal hysteresis VPRE = Output voltage measured at 25°C pretemperature cycling VPOST = Output voltage measured after the device has been cycled through the specified temperature range of –40°C to +125°C and returned to 25°C. VOUT 2 FIGURE 2. Typical Connections for Operating REF31xx. TEMPERATURE DRIFT The REF31xx is designed to exhibit minimal drift error, defined as the change in output voltage over varying temperature. The drift is calculated using the “box” method which is described by the following equation: SUPPLY VOLTAGE The REF31xx family of references features an extremely low dropout voltage. With the exception of the REF3112, which has a minimum supply requirement of 1.8V, these references can be operated with a supply of only 5mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load is shown in the typical curves. The REF31xx features a low quiescent current, which is extremely stable over changes in both temperature and supply. The typical room temperature quiescent current is   VOUTMAX – VOUTMIN • 10 6 ppm V • TemperatureRange   OUT  The REF31xx features a typical drift coefficient of 5ppm from 0°C to 70°C—the primary temperature range for many applications. For the industrial temperature range of –40°C to 125°C, the REF31xx family drift increases to a typical value of 10ppm. REF3112, 3120, 3125, 3130, 3133, 3140 SBVS046C 7 www.ti.com NOISE PERFORMANCE Typical 0.1Hz to 10Hz voltage noise can be seen in the Typical Characteristic Curve, 0.1 to 10Hz Voltage Noise. The noise voltage of the REF31xx increases with output voltage and operating temperature. Additional filtering may be used to improve output noise levels, although care should be taken to ensure the output impedance does not degrade the AC performance. LONG-TERM STABILITY Long-term stability refers to the change of the output voltage of a reference over a period of months or years. This effect lessens as time progresses, as is shown by the long-term stability curves. The typical drift value for the REF31xx is 70ppm from 0-1000 hours. This parameter is characterized by measuring 30 units at regular intervals for a period of 1000 hours. LOAD REGULATION Load regulation is defined as the change in output voltage due to changes in load current. The load regulation of the REF31xx is measured using force and sense contacts as pictured in Figure 4. The force and sense lines reduce the impact of contact and trace resistance, resulting in accurate measurement of the load regulation contributed solely by the REF31xx. For applications requiring improved load regulation, force and sense lines should be used. APPLICATION CIRCUITS Negative Reference Voltage For applications requiring a negative and positive reference voltage, the REF31xx and OPA703 can be used to provide a dual supply reference from a ±5V supply. Figure 5 shows the REF3125 used to provide a ±2.5V supply reference voltage. The low drift performance of the REF31xx complement the low offset voltage and low drift of the OPA703 to provide an accurate solution for split-supply applications. +5V REF3125 10kΩ +2.5V 10kΩ +5V OPA703 –2.5V –5V FIGURE 5.
