REF3033-Q1 Not Recommended For New Designs SBVS131–JANUARY2010 www.ti.com THEORY OF OPERATION The REF30xx is a series, CMOS, precision bandgap voltage reference. Its 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-emitter voltages, V – V , has a positive temperature coefficient and is forced be1 be2 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 temperaturecoefficientofthebase-emittervoltageofQ2. R + + 1 Vbe Vbe 1 2 – – Q Q 1 2 Figure1. SimplifiedSchematicofBandgapReference APPLICATION INFORMATION For normal operation, the REF30xx does not require a capacitor on the output. If a capacitive load is connected, special care must be taken with the combination of low equivalent series resistance (ESR) capacitors and high capacitance. This caution is especially true for low-output voltage devices; therefore, the REF3012 should only have a low-ESR capacitance of 10 μF or less. Figure 2 shows the typical connections required for operation of theREF30xx.Asupplybypasscapacitorof0.47μFisalwaysrecommended. VIN 1 0.47µF REF30xx 3 VOUT 2 Figure2. TypicalConnectionsforOperatingREF30xx Supply Voltage The REF30xx family of references features an extremely low dropout voltage. With the exception of the REF3012, which has a minimum supply requirement of 1.8 V, the REF30xx can be operated with a supply of only 1 mV above the output voltage in an unloaded condition. For loaded conditions, a typical dropout voltage versusloadisshownonthecoverpage. The REF30xx features a low quiescent current, which is extremely stable over changes in both temperature and supply. The typical room temperature quiescent current is 42 μA, and the maximum quiescent current over temperature is just 59 μA. Additionally, the quiescent current typically changes less than 2.5 μA over the entire supplyrange,asshowninFigure3. 8 SubmitDocumentationFeedback Copyright©2010,TexasInstrumentsIncorporated ProductFolderLink(s):REF3033-Q1

SupplyCurrentvsSupplyVoltage Supply voltages below the specified levels can cause the REF30xx to momentarily draw currents greater than the typical quiescent current. Using a power supply with a fast rising edge and low output impedance easily preventsthis. Thermal Hysteresis Thermal hysteresis for the REF30xx 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: Where V =Calculatedhysteresis HYST V =Outputvoltagemeasuredat25°Cpretemperaturecycling PRE V = Output voltage measured when device has been operated at 25°C, cycled through specified range POST –40°Cto85°C,andreturnedtooperationat25°C. Temperature Drift The REF30xx 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 REF30xx features a typical drift coefficient of 20 ppm from 0°C to 70°C—the primary temperature range of use for many applications. For automotive temperaturerangesof–40°Cto85°C,theREF30xxfamilydriftincreasestoatypicalvalueof50ppm. Noise Performance The REF30xx generates noise less than 50 μVp-p between frequencies of 0.1 Hz to 10 Hz, and can be seen in the typical characteristic curve "0.1 to 10Hz Voltage Noise." The noise voltage of the REF30xx increases with output voltage and operating temperature. Additional filtering may be used to improve output noise levels, althoughcareshouldbetakentoensuretheoutputimpedancedoesnotdegradeACperformance. 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 REF30xx is 24 ppm from 0 to 1000 hours and 15 ppm from 1000 to 2000 hours. This parameter is characterizedbymeasuring30unitsatregularintervalsforaperiodof2000hours. Copyright©2010,TexasInstrumentsIncorporated SubmitDocumentationFeedback 9 ProductFolderLink(s):REF3033-Q1
