(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 LM4050-N,
TJmax = 150°C, and the typical thermal resistance (RθJA), when board mounted, is 326°C/W for the SOT-23 package.
(4) High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.

(1) Limits are 100% production tested at 25°C. Limits over temperature are guaranteed through correlation using Statistical Quality Control
(SQC) methods. The limits are used to calculate National's 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: ±0.425% = ±0.1% ±50 ppm/°C ×
65°C B-grade: ±0.525% = ±0.2% ±50 ppm/°C × 65°C C-grade: ±0.825% = ±0.5% ±50 ppm/°C × 65°C. Therefore, as an
example, the A-grade LM4050-N-2.5 has an overtemperature Reverse Breakdown Voltage tolerance of ±2.5V × 0.425% = ±11 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.

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
tolerance accuracies are ±0.1%, ±0.2%, and ±0.5% for Versions A, B, and C, respectively. The LM4050-N comes
in two application versions, Industrial and Extended temperature range, which are operational from –40°C to
85°C and –40°C to 125°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
anode which is dependent on the current being supplied to the cathode. This current is needed for the LM4050-N
to regulate within the specified limits. Refer to the minimum and maximum operating requirements for the specific
voltage option used. The LM4050-N is internally compensated to be stable without the use of an output
capacitor. However, if desired, a bypass capacitor may be used.
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
cathode within the limits specified for the fixed-voltage version being used.

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 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. All versions have a maximum operating current of 15 mA.
LM4050-Ns in the SOT-23 packages have a parasitic Schottky diode between pin 2 () and pin 3 (Die attach
interface contact). Therefore, pin 3 of the SOT-23 package must be left floating or connected to pin 2.
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
ADCs or DACs that operate on supplies of 10 V or greater, the 8.192-V version gives 2 mV per LSB.
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 VOUT delta shift between the
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
and board mounting temperature are all factors that can contribute to thermal hysteresis.
In a conventional shunt regulator application (Figure 10) , an external series resistor (RS) is connected between
the supply voltage and the LM4050-N. RSdetermines the current that flows through the load (IL) and the
LM4050-N (IQ). Since load current and supply voltage may vary, RSshould be small enough to supply at least
the maximum guaranteed IRMIN (spec. table) to the LM4050-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 ILis at its
minimum, RSshould be large enough so that the current flowing through the LM4050-N is less than 15 mA.
RSis determined by the supply voltage, (VS), the load and operating current, (ILand IQ), and the LM4050-N's
reverse breakdown voltage, VR.

10 Power Supply Recommendations
Noise on the power supply input to RScan affect output noise performance. Noise performance can be reduced
by using an optional bypass capacitor at the input side of RSand Ground. TI recommends a 0.1-µF ceramic
capacitor or higher.
11 Layout
11.1 Layout Guidelines
Place RSas close to the cathode as possible. If an input and output capacitor is used, place this as close to the
reference as possible.

(1) The marketing status values are defined as follows:
ACTIVE: Product device recommended for new designs.
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".
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 finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two
lines if the finish value exceeds the maximum column width.
