The advanced design of the LM4041-N eliminates the need for an external stabilizing capacitor while ensuring stability with any capacitive load, thus making the LM4041-N easy to use. Further reducing design effort is the availability of a fixed (1.225 V) and adjustable reverse breakdown voltage. The minimum operating current is 60 A for the LM4041-N 1.2 and the LM4041-N ADJ. Both versions have a maximum operating current of 12 mA. 1 * * * * * * * * * * * Qualified for Automotive Applications SEC-Q100 Qualified With the Following Results: - Device Temperature Grade 1: -40C to +125C Ambient Temperature Range - Device Temperature Grade 3: -40C to +85C Ambient Temperature Range (For SOT-23 Only) Available in Standard, AEC Q-100 Grade 1 (Extended Temperature Range), and Grade 3 (Industrial Temperature Range) Qualified Versions (SOT-23 Only) Small Packages: SOT-23, TO-92, and SC70 No Output Capacitor Required Tolerates Capacitive Loads Reverse Breakdown Voltage Options of 1.225 V and Adjustable Output Voltage Tolerance (A grade, 25C) = 0.1%(Maximum) Low Output Noise (10 Hz to 10kHz) = 20 Vrms Wide Operating Current Range of 60 A to 12 mA Industrial Temperature Range (LM4041A/B-N, LM4041-N-Q1A/Q1B) of -40C to +85C Extended Temperature Range (LM4041C/D/E-N, LM4041-N-Q1C/Q1D/Q1E) of -40C to +125C Low Temperature Coefficient of 100 ppm/C (Maximum) 2 Applications * * * * * * * The LM4041-N uses fuse and Zener-zap reverse breakdown or reference voltage trim during wafer sort to ensure that the prime parts have an accuracy of better than 0.1% (A grade) at 25C. Bandgap reference temperature drift curvature correction and low dynamic impedance ensure stable reverse breakdown voltage accuracy over a wide range of operating temperatures and currents.

These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications. The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature), JA (junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any temperature is PDmax = (TJmax - TA)/RJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4041-N, TJmax = 125C, and the typical thermal resistance (RJA), when board mounted, is 326C/W for the SOT-23 package, 415C/W for the SC70 package and 180C/W with 0.4-in lead length and 170C/W with 0.125-in lead length for the TO-92 package.

Limits over temperature are ensured through correlation using Statistical Quality Control (SQC) methods. The limits are used to calculate AOQL. Typicals are at TJ = 25C and represent most likely parametric norm. The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage Tolerance [(VRT)(max T)(VR)]. Where, VR/T is the VR temperature coefficient, maxT is the maximum difference in temperature from the reference point of 25 C to T MAX or TMIN, and VR is the reverse breakdown voltage.

The part has three different packages available to meet small footprint requirements. It is also available in five different tolerance grades. 8.2 Functional Block Diagram *LM4041-N ADJ only **LM4041-N 1.2 only 8.3 Feature Description The LM4041 is effectively a precision Zener diode. The part requires a small quiescent current for regulation, and regulates the output voltage by shunting more or less current to ground, depending on input voltage and load. The only external component requirement is a resistor between the cathode and the input voltage to set the input current. An external capacitor can be used on the input or output, but is not required.

The fixed output parts can only be used in closed-loop operation, as the feedback is internal. The adjustable option parts are most commonly operated in closed-loop mode, where the feedback node is tied to the output voltage through a resistor divider. The output voltage will remain as long as lR is between lRMIN and lRMAX; see LM4041-N-xx 1.2 Electrical Characteristics (Industrial Temperature Range). This part can also be used in open-loop mode to act as a comparator, driving the feedback node from another voltage source. 18 Submit Documentation Feedback Copyright (c) 1999-2016, Texas Instruments Incorporated Product Folder Links: LM4041-N LM4041-N-Q1 LM4041-N, LM4041-N-Q1 www.ti.com SNOS641G - OCTOBER 1999 - REVISED JANUARY 2016 9 Application and Implementation NOTE Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI's customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality. 9.1 Application Information The LM4041-N is a precision micro-power curvature-corrected bandgap shunt voltage reference. For spacecritical applications, the LM4041-N is available in the sub-miniature SOT-23 and SC70 surface-mount package. The LM4041-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 LM4041-N remains stable. Design effort is further reduced with the choice of either a fixed 1.2 V or an adjustable reverse breakdown voltage. The minimum operating current is 60 A for the LM4041-N 1.2 V and the LM4041-N ADJ. Both versions have a maximum operating current of 12 mA. LM4041-Ns using the SOT-23 package have pin 3 connected as the (-) output through the die attach interface of the package. Therefore, pin 3 of the LM4041-N 1.2 must be left floating or connected to pin 2 and pin 3 of the LM4041-N ADJ pinout. The LM4041-N devices using the SC70 package have pin 2 connected as the (-) output through the die attach interface of the package. Therefore, the LM4041-N pin 2 of the LM4041-N 1.2 must be left floating or connected to pin 1, and the pin 2 of the LM4041-N ADJ is the (-) output. The typical thermal hysteresis specification is defined as the change in 25C voltage measured after thermal cycling. The device is thermal cycled to temperature -40C and then measured at +25C. Next the device is thermal cycled to temperature 125C and again measured at 25C. The resulting VOUT delta shift between the 25C 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 and board mounting temperature are all factors that can contribute to thermal hysteresis. In a conventional shunt regulator application (Figure 17), an external series resistor (RS) is connected between the supply voltage and the LM4041-N. RS determines the current that flows through the load (IL) and the LM4041-N (IQ). Because load current and supply voltage may vary, RS must be small enough to supply at least the minimum acceptable IQ to the LM4041-N even when the supply voltage is at its minimum and the load current is at its maximum value. When the supply voltage is at its maximum and IL is at its minimum, RS must be large enough so that the current flowing through the LM4041-N is less than 12 mA. RS must be selected based on the supply voltage, (VS), the desired load and operating current, (IL and IQ), and the reverse breakdown voltage of the LM4041-N, VR. (1) The output voltage of the LM4041-N SDJ can be adjusted to any value in the range of 1.24 V through 10 V. It is a function of the internal reference voltage (VREF) and the ratio of the external feedback resistors as shown in Figure 19 . The output voltage is found using Equation 2. VO = VREF[(R2/R1) + 1] where * VO is the output voltage. (2) The actual value of the internal VREF is a function of VO. The corrected VREF is determined by Equation 3. VREF = VO (VREF/VO) + VY where * * VY = 1.240 V and VO = (VO - VY) (3) Copyright (c) 1999-2016, Texas Instruments Incorporated Product Folder Links: LM4041-N LM4041-N-Q1 Submit Documentation Feedback 19 LM4041-N, LM4041-N-Q1 SNOS641G - OCTOBER 1999 - REVISED JANUARY 2016 www.ti.com Application Information (continued) VREF/VO is found in the electrical characteristics tables in the Specifications and is typically -1.55 mV/V. You can get a more accurate indication of the output voltage by replacing the value of VREF in Equation 2 with the value found using Equation 3. NOTE The actual output voltage can deviate from that predicted using the typical value of VREF / VO in Equation 3. For C-grade parts, the worst-case VREF / VO is -2.5 mV/V. For D-grade parts, the worst-case VREF / VO is -3.0 mV/V. 9.2 Typical Applications 9.2.1 Shunt Regulator Figure 17. Shunt Regulator 9.2.1.1 Design Requirements VIN > VOUT Select RS with Equation 4. lRMIN < lR < lRMAX = 15 mA (4) See the electrical characteristics tables in the Specifications for minimum operating current for each voltage option and grade. 9.2.1.2 Detailed Design Procedure The resistor RS must be selected such that current lR remains in the operational region of the part for the entire VIN range and load current range. At its maximum, the RS must be small enough for lR to remain above lRMN. The other extreme is when VIN at its maximum and the load at its minimum; the RS must be large enough to maintain lR < lRMAX. If unsure, try using 0.1 mA lR 1 mA as starting point. Just remember the value of lR varies with input and voltage load. Use equations Equation 5 and Equation 6 to set RS between RS_MIN and RS_MAX.

Use Equation 11, but in this case, take the negative supply into account. lR = (VIN - VOUT) /R lR = (VIN+ - VIN - VOUT) / R = (30 V - 10 V) / (RS1 + RS2) = 20 V / 30 k = 0.667 mA (11) (12) This is an acceptable value for lR that does not draw excessive current, but prevents the part from being starved for current. 22 Submit Documentation Feedback Copyright (c) 1999-2016, Texas Instruments Incorporated Product Folder Links: LM4041-N LM4041-N-Q1 LM4041-N, LM4041-N-Q1 www.ti.com SNOS641G - OCTOBER 1999 - REVISED JANUARY 2016 Typical Applications (continued) 9.2.3.3 Application Curve Figure 21.

A 0.1-F ceramic capacitor or larger is recommended. 11 Layout 11.1 Layout Guidelines Place external components as close to the device as possible. Place RS close the cathode, as well as the input bypass capacitor, if used. Keep feedback resistor close the device whenever possible. 11.2 Layout Example Figure 33.
