The LM4130 family of precision voltage references
performs comparable to the best laser-trimmed
bipolar references, but in cost effective CMOS
technology. Key to this break through is the use of
EEPROM registers for correction of curvature,
tempco, and accuracy on a CMOS bandgap
architecture that allows package level programming
to overcome assembly shift. The shifts in voltage
accuracy and tempco during assembly of die into
plastic packages limit the accuracy of references
trimmed with laser techniques.

Unlike other LDO references, the LM4130 requires no
output capacitor. Neither is a buffer amplifier required,
even with loads up to 20mA. These advantages and
the SOT23 packaging are important for cost-critical
and space-critical applications.
Series references provide lower power consumption
than shunt references, since they don't have to idle
the maximum possible load current under no load
conditions. This advantage, the low quiescent current
(75µA), and the low dropout voltage(275mV) make
the LM4130 ideal for battery-powered solutions.
The LM4130 is available in five grades (A, B, C, D
and E) for greater flexibility. The best grade devices
(A) have an initial accuracy of 0.05% with ensured
temperature coefficient of 10ppm/°C or less, while the
lowest grade parts (E) have an initial accuracy of
0.5% and a tempco of 30ppm/°C.

which the device is intended to be functional, but do not ensure specific performance limits. For ensured specifications and test
conditions, see 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.
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 SOT235 package is 220°C/W, TJMAX = 125°C.
The human body model is a 100 pF capacitor discharged through a 1.5 kΩ resistor into each pin. The machine model is a 200 pF
capacitor discharged directly into each pin.

Output Noise Spectra
Pin Functions
VREF (Pin 5): Reference Output. The output of the LM4130 can source up to 20 mA. It is stable with output
capacitor ranges from 0 to 100 µF.
VIN (Pin 4): Positive Supply. Bypassing with a 0.1µF capacitor is recommended if the output loading changes or
input is noisy.
Ground (Pin 2): Negative Supply or Ground Connection.
NC (Pins 1, 3): No Connection (internally terminated). These pins must be left unconnected.
Application Information
OUTPUT CAPACITOR
The LM4130 is designed to operate with or without an output capacitor and is stable with capacitive loads of up
to 100 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. However, the output capacitor should not be made arbitrarily
large because it will effect the turn-on time as well as line and load transients.
INPUT CAPACITOR
A small 0.1µF capacitor on the input significantly improves stability under a wide range of load conditions. With
an input bypass capacitor, the LM4130 will drive any combination of resistance and capacitance up to
VREF/20mA and 100 µF respectively.
Noise on the power-supply input can effect the output noise, but it can be reduced by using an optional bypass
capacitor between the input pin and the ground.

PRINTED CIRCUIT BOARD LAYOUT CONSIDERATION
References in SOT packages are generally less prone to assembly stress than devices in Small Outline (SOIC)
package.
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.

* Select R1 to deliver 80% of typical load current. The LM4130 then will source as necessary, up to 20mA, to maintain

approach will effect line regulation.

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.
