FEATURES
DESCRIPTION
Ideal for space critical applications, the LM4128
precision voltage reference is available in the SOT-23
surface-mount package. The LM4128’s advanced
design eliminates the need for an external stabilizing
capacitor while ensuring stability with capacitive loads
up to 10 µF, thus making the LM4128 easy to use.

Output Voltage Initial Accuracy 0.1%
Low Temperature Coefficient 75 ppm/°C
Low Supply Current, 60 µA
Enable Pin Allowing a 3 µA Shutdown Mode
Up to 20 mA Output Current
Series references provide lower power consumption
than shunt references, since they do not have to idle
the maximum possible load current under no load
conditions. This advantage, the low quiescent current
(60 µA), and the low dropout voltage (400 mV) make
the LM4128 ideal for battery-powered solutions.

(1) Absolute Maximum Ratings indicate limits beyond which damage may occur to the device. Operating Ratings indicate conditions for
which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications, see Electrical
Characteristics.
(2) Without PCB copper enhancements. The maximum power dissipation must be de-rated at elevated temperatures and is limited by TJMAX
(maximum junction temperature), θJ-A (junction to ambient thermal resistance) and TA (ambient temperature). The maximum power
dissipation at any temperature is: PDissMAX = (TJMAX - TA) /θJ-A up to the value listed in the Absolute Maximum Ratings. θJ-A for SOT-23
package is 220°C/W, TJMAX = 125°C.
(3) The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin.

APPLICATION INFORMATION
THEORY OF OPERATION
The foundation of any voltage reference is the band-gap circuit. While the reference in the LM4128 is developed
from the gate-source voltage of transistors in the IC, principles of the band-gap circuit are easily understood
using a bipolar example. For a detailed analysis of the bipolar band-gap circuit, see the AN-56 Application Report
(SNVA514).
SUPPLY AND ENABLE VOLTAGES
To ensure proper operation, VEN and VIN must be within a specified range. An acceptable range of input voltages
is
VIN > VREF + 400 mV (ILOAD ≤ 10 mA)
(1)
The enable pin uses an internal pull-up current source (IPULL_UP ≊ 2 µA) that may be left floating or triggered by
an external source. If the part is not enabled by an external source, it may be connected to VIN. An acceptable
range of enable voltages is given by the enable transfer characteristics. See the Electrical Characteristics section
and Enable Transfer Characteristics figure for more detail. Note, the part will not operate correctly for VEN > VIN.
COMPONENT SELECTION
A small ceramic (X5R or X7R) capacitor on the input must be used to ensure stable operation. The value of CIN
must be sized according to the output capacitor value. The value of CIN must satisfy the relationship CIN ≥ COUT
.
When no output capacitor is used, CIN must have a minimum value of 0.1 µF. Noise on the power-supply input
may affect the output noise. Larger input capacitor values (typically 4.7 µF to 22 µF) may help reduce noise on
the output and significantly reduce overshoot during startup. Use of an additional optional bypass capacitor
between the input and ground may help further reduce noise on the output. With an input capacitor, the LM4128
will drive any combination of resistance and capacitance up to VREF/20 mA and 10 µF respectively.
The LM4128 is designed to operate with or without an output capacitor and is stable with capacitive loads up to
10 µF. Connecting a capacitor between the output and ground will significantly improve the load transient
response when switching from a light load to a heavy load. The output capacitor should not be made arbitrarily
large because it will effect the turn-on time as well as line and load transients.
While a variety of capacitor chemistry types may be used, it is typically advisable to use low esr ceramic
capacitors. Such capacitors provide a low impedance to high frequency signals, effectively bypassing them to
ground. Bypass capacitors should be mounted close to the part. Mounting bypass capacitors close to the part will
help reduce the parasitic trace components thereby improving performance.
SHORT CIRCUITED OUTPUT
The LM4128 features indefinite short circuit protection. This protection limits the output current to 75 mA when
the output is shorted to ground.
TURN ON TIME
Turn on time is defined as the time taken for the output voltage to rise to 90% of the preset value. The turn on
time depends on the load. The turn on time is typically 33.2 µs when driving a 1µF load and 78.8 µs when driving
a 10 µF load. Some users may experience an extended turn on time (up to 10 ms) under brown out conditions
and low temperatures (-40°C).
THERMAL HYSTERESIS
Thermal hysteresis is defined as the change in output voltage at 25ºC after some deviation from 25ºC. This is to
say that thermal hysteresis is the difference in output voltage between two points in a given temperature profile.
An illustrative temperature profile is shown in Figure 16.

•
•
TD = Temperature drift
VREF = Nominal preset output voltage
VREF_MIN = Minimum output voltage over operating temperature range
VREF_MAX = Maximum output voltage over operating temperature range
ΔT = Operating temperature range
(3)
The LM4128 features a low temperature drift of 75 ppm (max) to 100 ppm (max), depending on the grade, from -
40°C to 125°C.
LONG TERM STABILITY
Long-term stability refers to the fluctuation in output voltage over a long period of time (1000 hours). The LM4128
features a typical long-term stability of 50 ppm over 1000 hours. The measurements are made using 5 units of
each voltage option, at a nominal input voltage (5V), with no load, at room temperature.
EXPRESSION OF ELECTRICAL CHARACTERISTICS
Electrical characteristics are typically expressed in mV, ppm, or a percentage of the nominal value. Depending
on the application, one expression may be more useful than the other. To convert one quantity to the other one
may apply the following:
ppm to mV error in output voltage:
VREF x ppmERROR
= VERROR
103
where
•
VREF is in volts (V) and VERROR is in milli-volts (mV)
(4)
Bit error (1 bit) to voltage error (mV):
VREF
2n
x 103
= VERROR
where

•
VREF is in volts (V)
VERROR is in milli-volts (mV)
and n is the number of bits

PRINTED CIRCUIT BOARD and LAYOUT CONSIDERATIONS
References in SOT packages are generally less prone to PC board mounting than devices in Small Outline
(SOIC) packages. To minimize the mechanical stress due to PC board mounting that can cause the output
voltage to shift from its initial value, mount the reference on a low flex area of the PC board, such as near the
edge or a corner.
The part may be isolated mechanically by cutting a U shape slot on the PCB for mounting the device. This
approach also provides some thermal isolation from the rest of the circuit.
Bypass capacitors must be mounted close to the part. Mounting bypass capacitors close to the part will reduce
the parasitic trace components thereby improving performance.

(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) Eco Plan - The planned eco-friendly classification: Pb-Free (RoHS), Pb-Free (RoHS Exempt), or Green (RoHS & no Sb/Br) - please check http://www.ti.com/productcontent for the latest availability
information and additional product content details.
TBD: The Pb-Free/Green conversion plan has not been defined.
Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
(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.

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other
changes to its semiconductor products and services per JESD46, latest issue, and to discontinue any product or service per JESD48, latest
issue. Buyers should obtain the latest relevant information before placing orders and should verify that such information is current and
complete. All semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale
supplied at the time of order acknowledgment.
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily
performed.
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the
third party, or a license from TI under the patents or other intellectual property of TI.
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered
documentation. Information of third parties may be subject to additional restrictions.
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.
TI is not responsible or liable for any such statements.
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use
of any TI components in safety-critical applications.
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and
requirements. Nonetheless, such components are subject to these terms.
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties
have executed a special agreement specifically governing such use.
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and
regulatory requirements in connection with such use.
TI has specifically designated certain components as meeting ISO/TS16949 requirements, mainly for automotive use. In any case of use of
non-designated products, TI will not be responsible for any failure to meet ISO/TS16949.
