3 Description
Ideal for space-critical applications, the LM4040-N
precision voltage reference is available in the sub-
miniature SC70 and SOT-23 surface-mount package.
The advanced design of the LM4040-N eliminates the
need for an external stabilizing capacitor while
ensuring stability with any capacitive load, thus
making the LM4040-N easy to use. Further reducing
design effort is the availability of several fixed reverse
breakdown voltages: 2.048 V, 2.5 V, 3 V, 4.096 V, 5
V, 8.192 V, and 10 V. The minimum operating current
increases from 60 μA for the 2.5-V LM4040-N to 100
μA for the 10-V LM4040-N. All versions have a
maximum operating current of 15 mA.
The LM4040-N uses a fuse and Zener-zap reverse
breakdown voltage trim during wafer sort to ensure
that the prime parts have an accuracy of better than
±0.1% (A grade) at 25°C. 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.
Also available is the LM4041-N with two reverse
breakdown voltage versions: adjustable and 1.2 V.
See the LM4041-N data sheet (SNOS641).

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. 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.
(2) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and
specifications.
(3) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
RθJA (junction to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax −TA)/RθJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040-N,
TJmax = 125°C, and the typical thermal resistance (RθJA), when board mounted, is 326°C/W for the SOT-23 package, and 180°C/W with
0.4″lead length and 170°C/W with 0.125″lead length for the TO-92 package and 415°C/W for the SC70 Package.
(4) For definitions of Peak Reflow Temperatures for Surface Mount devices, see the TI Absolute Maximum Ratings for Soldering Application
Report (SNOA549).

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Recommended Operating Conditions indicate
conditions for which the device is functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see the Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance
characteristics may degrade when the device is not operated under the listed test conditions.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
RθJA (junction to ambient thermal resistance), and TA(ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax −TA)/RθJA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LM4040-N,
TJmax = 125°C, and the typical thermal resistance (RθJA), when board mounted, is 326°C/W for the SOT-23 package, and 180°C/W with

(1) Limits are 100% production tested at 25°C. Limits over temperature are ensured through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate AOQL.
(2) The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage
Tolerance ±[(ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VRtemperature coefficient, maxΔT is the maximum difference in temperature
from the reference point of 25°C to T MIN or TMAX, and VRis the reverse breakdown voltage. The total overtemperature tolerance for the
different grades in the industrial temperature range where maxΔT = 65°C is shown below:
A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C
B-grade: ±0.85% = ±0.2% ±100 ppm/°C × 65°C
C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C
D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C
E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C
The total overtemperature tolerance for the different grades in the extended temperature range where max ΔT = 100 °C is shown below:
C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C
D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C
E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C
Therefore, as an example, the A-grade 2.5-V LM4040-N has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5 V ×
0.75% = ±19 mV.
(3) Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change
must be taken into account separately.
(4) Thermal hysteresis is defined as the difference in voltage measured at 25°C after cycling to temperature -40°C and the 25°C
measurement after cycling to temperature 125°C.

(1) Limits are 100% production tested at 25°C. Limits over temperature are ensured through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate AOQL.
(2) Typicals are at TJ= 25°C and represent most likely parametric norm.
(3) The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage
Tolerance ±[(ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VRtemperature coefficient, maxΔT is the maximum difference in temperature
from the reference point of 25°C to T MIN or TMAX, and VRis the reverse breakdown voltage. The total overtemperature tolerance for the
different grades in the industrial temperature range where maxΔT = 65°C is shown below:
A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C
B-grade: ±0.85% = ±0.2% ±100 ppm/°C × 65°C
C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C
D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C
E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C
The total overtemperature tolerance for the different grades in the extended temperature range where max ΔT = 100 °C is shown below:
C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C
D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C
E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C
Therefore, as an example, the A-grade 2.5-V LM4040-N has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5V ×
0.75% = ±19 mV.
(4) Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change
must be taken into account separately.

(1) Limits are 100% production tested at 25°C. Limits over temperature are ensured through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate AOQL.
(2) Typicals are at TJ= 25°C and represent most likely parametric norm.
(3) The overtemperature limit for Reverse Breakdown Voltage Tolerance is defined as the room temperature Reverse Breakdown Voltage
Tolerance ±[(ΔVR/ΔT)(maxΔT)(VR)]. Where, ΔVR/ΔT is the VRtemperature coefficient, maxΔT is the maximum difference in temperature
from the reference point of 25°C to T MIN or TMAX, and VRis the reverse breakdown voltage. The total overtemperature tolerance for the
different grades in the industrial temperature range where maxΔT = 65°C is shown below:
A-grade: ±0.75% = ±0.1% ±100 ppm/°C × 65°C
B-grade: ±0.85% = ±0.2% ±100 ppm/°C × 65°C
C-grade: ±1.15% = ±0.5% ±100 ppm/°C × 65°C
D-grade: ±1.98% = ±1.0% ±150 ppm/°C × 65°C
E-grade: ±2.98% = ±2.0% ±150 ppm/°C × 65°C
The total overtemperature tolerance for the different grades in the extended temperature range where max ΔT = 100 °C is shown below:
C-grade: ±1.5% = ±0.5% ±100 ppm/°C × 100°C
D-grade: ±2.5% = ±1.0% ±150 ppm/°C × 100°C
E-grade: ±3.5% = ±2.0% ±150 ppm/°C × 100°C
Therefore, as an example, the A-grade 2.5-V LM4040-N has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5V ×
0.75% = ±19 mV.
(4) Load regulation is measured on pulse basis from no load to the specified load current. Output changes due to die temperature change
must be taken into account separately.
(5) Thermal hysteresis is defined as the difference in voltage measured at +25°C after cycling to temperature -40°C and the 25°C
measurement after cycling to temperature 125°C.
