LM4050-N,LM4050-N-Q1 www.ti.com SNOS455G–MAY2000–REVISEDSEPTEMBER2015 8 Detailed Description 8.1 Overview The LM4050-N device is a precision micropower shunt voltage reference. The part comes in 6 different fixed- output voltage options for space-constrained applications, removing the need for feedback resistors. The voltage toleranceaccuraciesare±0.1%, ±0.2%,and±0.5%forVersionsA,B,andC,respectively.TheLM4050-Ncomes in two application versions, Industrial and Extended temperature range, which are operational from –40°C to 85°Cand–40°Cto125°C,respectively. 8.2 Functional Block Diagram 8.3 Feature Description The LM4050-N behaves as a high-precision Zener diode. The voltage is regulated between its cathode and anodewhichisdependentonthecurrentbeingsuppliedtothecathode.ThiscurrentisneededfortheLM4050-N toregulatewithinthespecifiedlimits.Refertotheminimumandmaximumoperatingrequirementsforthespecific voltage option used. The LM4050-N is internally compensated to be stable without the use of an output capacitor.However,ifdesired,abypasscapacitormaybeused. 8.4 Device Functional Modes The LM4050-N can only operate in closed loop due to the fact that the feedback resistors are internal to the device. Additionally, the output voltage cannot be adjusted for the same reason. The output voltage is regulated in a closed loop, provided the Rs (see Functional Block Diagram) resistor is sized to deliver the current to the cathodewithinthelimitsspecifiedforthefixed-voltageversionbeingused.

TI’s customers are responsible for determining suitability of components for their purposes. Customers should validateandtesttheirdesignimplementationtoconfirmsystemfunctionality. 9.1 Application Information The LM4050-N is a precision micropower curvature-corrected bandgap shunt voltage reference. For space critical applications, the LM4050-N is available in the sub-miniature SOT-23 surface-mount package. The LM4050-N has been designed for stable operation without the need of an external capacitor connected between the + pin and the − pin. If, however, a bypass capacitor is used, the LM4050-N remains stable. Reducing design effort is the availability of several fixed reverse breakdown voltages: 2.048 V, 2.5 V, 4.096 V, 5 V, 8.192 V, and 10 V. The minimum operating current increases from 60 μA for the LM4050-N-2.0 to 100 μA for the LM4050-N- 10.0.Allversionshaveamaximumoperatingcurrentof15mA. LM4050-Ns in the SOT-23 packages have a parasitic Schottky diode between pin 2 (−) and pin 3 (Die attach interfacecontact).Therefore,pin3oftheSOT-23packagemustbeleftfloatingorconnectedtopin2. The 4.096-V version allows single 5-V 12-bit ADCs or DACs to operate with an LSB equal to 1 mV. For 12-bit ADCsorDACsthatoperateonsuppliesof10Vorgreater,the8.192-Vversiongives2mVperLSB. The typical thermal hysteresis specification is defined as the change in 25°C voltage measured after thermal cycling. The device is thermal cycled to temperature –40°C and then measured at 25°C. Next the device is thermal cycled to temperature 125°C and again measured at 25°C. The resulting V delta shift between the OUT 25°C measurements is thermal hysteresis. Thermal hysteresis is common in precision references and is induced by thermal-mechanical package stress. Changes in environmental storage temperature, operating temperature andboardmountingtemperatureareallfactorsthatcancontributetothermalhysteresis. In a conventional shunt regulator application (Figure 10) , an external series resistor (R ) is connected between S the supply voltage and the LM4050-N. R determines the current that flows through the load (I ) and the S L LM4050-N (I ). Since load current and supply voltage may vary, R should be small enough to supply at least Q S the maximum guaranteed I (spec. table) to the LM4050-N even when the supply voltage is at its minimum RMIN and the load current is at its maximum value. When the supply voltage is at its maximum and I is at its L minimum,R shouldbelargeenoughsothatthecurrentflowingthroughtheLM4050-Nislessthan15mA. S R is determined by the supply voltage, (V ), the load and operating current, (I and I ), and the LM4050-N's S S L Q reversebreakdownvoltage,V .

Noise performance can be reduced S by using an optional bypass capacitor at the input side of R and Ground.

LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect. NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design. PREVIEW: Device has been announced but is not in production. Samples may or may not be available. OBSOLETE: TI has discontinued the production of the device. (2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may reference these types of products as "Pb-Free". Addendum-Page 6

PACKAGE OPTION ADDENDUM www.ti.com 8-Mar-2019 RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption. Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based flame retardants must also meet the <=1000ppm threshold requirement. (3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature. (4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device. (5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation of the previous line and the two combined represent the entire Device Marking for that device. (6) Lead/Ball Finish - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead/Ball Finish values may wrap to two lines if the finish value exceeds the maximum column width.
