DESCRIPTION
The LM4140 series of precision references are
designed to combine high accuracy, low drift and
noise with low power dissipation in a small package.
The LM4140 is the industry's first reference with
output voltage options lower than the bandgap
voltage.
The key to the advance performance of the LM4140
is the use of EEPROM registers and CMOS DACs for
temperature coefficient curvature correction and
trimming of the output voltage accuracy of the device
during the final production testing.
The major advantage of this method is the much
higher resolution available with DACs than is
available economically with most methods utilized by
other bandgap references.
The low input and dropout voltage, low supply current
and output drive capability of the LM4140 makes this
product an ideal choice for battery powered and
portable applications.
The LM4140 is available in three grades (A, B, C)
with 0.1% initial accuracy and 3, 6 and 10 ppm/°C
temperature coefficients. For even lower Tempco,
contact Texas Instruments.
The device performance is specified over the
temperature range (0°C to +70°C) and is available in
compact 8-pin package.
For other output voltage options from 0.5V to
4.5V, contact Texas Instruments.

For proper operation, a 1μF capacitor is required between the output pin and the GND pin of the device. (See Application Hints for
details)
Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlation using Statistical
Quality Control (SQC) methods. The limits are used to calculate TI's Average Outgoing Quality Level (AOQL).
Typical numbers are at 25°C and represent the most likely parametric norm.
High temperature and mechanical stress associated with PCB assembly can have significant impact on the initial accuracy of the
LM4140 and may create significant shifts in VREF. See Application Hints section regarding accuracy and PCB layout consideration.

APPLICATION HINTS
INPUT CAPACITORS
Although not always required, an input capacitor is recommended. A supply bypass capacitor on the input
assures that the reference is working from a source with low impedance, which improves stability. A bypass
capacitor can also improve transient response by providing a reservoir of stored energy that the reference can
utilize in case where the load current demand suddenly increases. The value used for CIN may be used without
limit. Refer to the Typical Application section for examples of input capacitors.
OUTPUT CAPACITORS
The LM4140 requires a 1μF (nominally) output capacitor for loop stability (compensation) as well as transient
response. During the sudden changes in load current demand, the output capacitor must source or sink current
during the time it takes the control loop of the LM4140 to respond.
This capacitor must be selected to meet the requirements of minimum capacitance and equivalent series
resistance (ESR) range.
In general, the capacitor value must be at least 0.2μF (over the actual ambient operating temperature), and the
ESR must be within the range indicated in Figure 24, Figure 25 and Figure 26.

TANTALUM CAPACITORS
Surface-mountable solid tantalum capacitors offer a good combination of small physical size for the capacitance
value, and ESR in the range needed for by the LM4140. The results of testing the LM4140 stability with surface
mount solid tantalum capacitors show good stability with values in the range of 0.1μF. However, optimum
performance is achieved with a 1μF capacitor.
Tantalum capacitors that have been verified as suitable for use with the LM4140 are shown in Table 1.

ALUMINUM ELECTROLYTIC CAPACITORS
Although probably not a good choice for a production design, because of relatively large physical size, an
aluminium electrolytic capacitor can be used in the design prototype for an LM4140 reference. A 1μF capacitor
meeting the ESR conditions can be used. If the operating temperature drops below 0°C, the reference may not
remain stable, as the ESR of the aluminium electrolytic capacitor will increase, and may exceed the limits
indicated in the figures.
MULTILAYER CERAMIC CAPACITORS
Surface-mountable multilayer ceramic capacitors may be an attractive choice because of their relatively small
physical size and excellent RF characteristics.

However, they sometimes have an ESR values lower than the minimum required by the LM4140, and relatively
large capacitance change with temperature. The manufacturer's datasheet for the capacitor should be consulted
before selecting a value. Test results of LM4140 stability using multilayer ceramic capacitors show that a
minimum of 0.2μF is usually needed.
Multilayer ceramic capacitors that have been verified as suitable for use with the LM4140 are shown in Table 2.

REVERSE CURRENT PATH
The P-channel Pass transistor used in the LM4140 has an inherent diode connected between the VIN and VREF
pins (see diagram below).
Forcing the output to voltages higher than the input, or pulling VIN below voltage stored on the output capacitor
by more than a Vbe, will forward bias this diode and current will flow from the VREF terminal to VIN. No damage to
the LM4140 will occur under these conditions as long as the current flowing into the output pin does not exceed
50mA.
ON/OFF OPERATION
The LM4140 is designed to quickly reduce both VREF and IQ to zero when turned-off. VREF is restored in less than
200μs when turned-on. During the turn-off, the charge across the output capacitor is discharged to ground
through internal circuitry.
The LM4140 is turned-off by pulling the enable input low, and turned-on by driving the input high. If this feature is
not to be used, the enable pin should be tied to the VIN to keep the reference on at all times (the enable pin must
not be left floating).
To ensure proper operation, the signal source used to drive the enable pin must be able to swing above and
below the specified high and low voltage thresholds which ensure an ON or OFF state (see LM4140
Electrical Charateristics).
The ON/OFF signal may come from either a totem-pole output, or an open-collector output with pull-up resistor to
the LM4140 input voltage. This high-level voltage may exceed the LM4140 input voltage, but must remain within
the Absolute Maximum Rating for the enable pin.
OUTPUT ACCURACY
Like all references, either series or shunt, the after assembly accuracy is made up of primarily three components:
initial accuracy itself, thermal hysteresis and effects of the PCB assembly stress.
LM4140 provides an excellent output initial accuracy of 0.1% and temperature coefficient of 6ppm/°C (B Grade).
For best accuracy and precision, the LM4140 junction temperature should not exceed 70°C.
The thermal hysteresis curve on this datasheet are performance characteristics of three typical parts selected at
random from a sample of 40 parts.
Parts are mounted in a socket to minimize the effect of PCB's mechnical expansion and contraction. Readings
are taken at 25°C following multiple temperature cycles to 0°C and 70°C. The labels on the X axis of the graph
indicates the device temperature cycle prior to measurement at 25°C.

Figure 27. Typical Thermal Hysteresis
The mechanical stress due to the PCB's mechanical and thermal stress can cause an output voltage shift more
than the true thermal coefficient of the device. References in surface mount packages are more susceptible to
these stresses because of the small amount of plastic molding which support the leads.
Following the recommendations on PCB LAYOUT CONSIDERATION section can minimize the mechanical
stress on the device.
PCB LAYOUT CONSIDERATION
The simplest ways to reduce the stress related shifts are:
1. Mounting the device near the edges or the corners of the board where mechanical stress is at its minimum.
The center of the board generally has the highest mechanical and thermal expansion stress.
2. Mechanical isolation of the device by creating an island by cutting a U shape slot on the PCB for mounting
the device. This approach would also provide some thermal isolation from the rest of the circuit.
Figure 28 is a recommended printed board layout with a slot cut on three sides of the circuit layout to serve as a
strain relief.

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.
