It’s basic topology is shown in Figure 1. The 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-emiter 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 coefficient. The resulting output voltage is virtually independent of temperature. The curvature of the bandgap voltage, as seen in the typical curve, “Output Voltage vs Temperature”, is due to the slightly nonlinear temperature coefficient of the base-emitter voltage of Q2. The REF29xx features a low quiescent current, which is extremely stable over changes in both temperature and supply. The typical room temperature quiescent current is 42µA, and the maximum quiescent current over temperature is just 59µA. Additionally, the quiescent current typically changes less than 2.5µA over the entire supply range, as shown in Figure 3. 42.5 42.0 IQ (µA) 41.5 41.0 40.5 40.0 1 1.5 2 2.5 3 3.5 VIN (V) 4 4.5 5 5.5 6 + + Vbe1 Vbe2 – – R1 Q1 Q2 FIGURE 3. Supply Current vs Supply Voltage. Supply voltages below the specified levels can cause the REF29xx to momentarily draw currents greater than the typical quiescent current. Using a power supply with a fast rising edge and low output impedance easily prevents this. FIGURE 1. Simplified Schematic of Bandgap Reference. APPLICATION INFORMATION The REF29xx does not require a load capacitor, and is stable with any capacitive load. Figure 2 shows typical connections required for operation of the REF29xx. A supply bypass capacitor of 0.47µF is recommended. THERMAL HYSTERESIS Thermal hysteresis for the REF29xx 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, and can be expressed as:  abs VPRE – VPOST  6 VHYST =   • 10 (ppm) VNOM   VIN 1 0.47µF REF29xx 3 Where: VHYST = Calculated hysteresis VPRE = Output voltage measured at 25°C pretemperature cycling VPOST = Output voltage measured when device has been operated at 25°C, cycled through specified range –40°C to +125°C and returned to operation at 25°C VOUT 2 FIGURE 2. Typical Connections for Operating REF29xx. TEMPERATURE DRIFT The REF29xx is designed to exhibit minimal drift error, defined as the change in output voltage over varying temperature. Using the ‘box’ method of drift measurement, the REF29xx features a typical drift coefficient of 20ppm from 0°C to 70°C— the primary temperature range of use for many applications. For industrial temperature ranges of –40°C to 125°C, the REF29xx family drift increases to a typical value of 50ppm. SUPPLY VOLTAGE The REF29xx family of references features an extremely low dropout voltage. With the exception of the REF2912, which has a minimum supply requirement of 1.8V, the REF29xx can be operated with a supply of only 1mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versus load is shown on the cover page. 8 REF2912, 2920, 2925, 2930, 2933, 2940 www.ti.com SBVS033A NOISE PERFORMANCE The REF29xx generates noise less than 50µVp-p between frequencies of 0.1Hz to 10Hz, and can be seen in the Typical Characteristic Curve “0.1 to 10Hz Voltage Noise”. The noise voltage of the REF29xx 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 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 apparent by the long term stability curves. The typical drift value for the REF29xx is 24ppm from 0-1000 hours, and 15ppm from 1000-2000 hours. This parameter is characterized by measuring 30 units at regular intervals for a period of 2000 hours. LOAD REGULATION Load regulation is defined as the change in output voltage due to changes in load current. Load regulation for the REF29xx is measured using force and sense contacts as pictured in Figure 4. The force and sense lines tied to the contact area of the output pin reduce the impact of contact and trace resistance, resulting in accurate measurement of the load regulation contributed solely by the REF29xx. 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 OPA703 and REF29xx can be used to provide a dual supply reference from a ±5V supply. Figure 5 shows the REF2925 used to provide a ±2.5V supply reference voltage. The low offset voltage and low drift of the OPA703 complement the low drift performance of the REF29xx to provide an accurate solution for split-supply applications. +5V REF2925 10kΩ +2.5V 10kΩ +5V OPA703 –2.5V Output Pin + VOUT – Contact and Trace Resistance –5V FIGURE 5.

Customers should obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment. TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where mandated by government requirements, testing of all parameters of each product is not necessarily performed. TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and applications using TI components. To minimize the risks associated with customer products and applications, customers should provide adequate design and operating safeguards. TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right, or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information published by TI regarding third-party products or services does not constitute a license from TI to use such products or services or a warranty or endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the third party, or a license from TI under the patents or other intellectual property of TI. Reproduction of information in TI data books or data sheets is permissible only if reproduction is without alteration and is accompanied by all associated warranties, conditions, limitations, and notices. Reproduction of this information with alteration is an unfair and deceptive business practice. TI is not responsible or liable for such altered documentation. Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not responsible or liable for any such statements. TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in such safety-critical applications. TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use. TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated products in automotive applications, TI will not be responsible for any failure to meet such requirements.
