1FEATURES DESCRIPTION
2• LOW TEMPERATURE DRIFT: The REF50xx is a family of low-noise, low-drift, very
high precision voltage references. These references
– High-Grade: 3ppm/°C (max) are capable of both sinking and sourcing, and are
– Standard-Grade: 8ppm/°C (max) very robust with regard to line and load changes.
• HIGH ACCURACY: Excellent temperature drift (3ppm/°C) and high
– High-Grade: 0.05% (max) accuracy (0.05%) are achieved using proprietary
– Standard-Grade: 0.1% (max) design techniques. These features, combined with
very low noise, make the REF50xx family ideal for
• LOW NOISE: 3mVPP/V use in high-precision data acquisition systems.
• EXCELLENT LONG-TERM STABILITY: Each reference voltage is available in both standard-
– 5ppm/1000hr (typ) after 1000 hours and high-grade versions. They are offered in MSOP-8
• HIGH OUTPUT CURRENT: ±10mA and SO-8 packages, and are specified from –40°C to
• TEMPERATURE RANGE: –40°C to +125°C +125°C.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
The REF50xx is family of low-noise, precision requirement of 2.7V, these references can be
bandgap voltage references that are specifically operated with a supply of 200mV above the output
designed for excellent initial voltage accuracy and voltage in an unloaded condition. For loaded
drift. Figure 28 shows a simplified block diagram of conditions, a typical dropout voltage versus load plot
the REF50xx. is shown in Figure 6 of the Typical Characteristics.
OUTPUT ADJUSTMENT USING THE TRIM/NR
PIN
The REF50xx provides a very accurate,
factory-trimmed voltage output. However, VOUT can
be adjusted using the trim and noise reduction pin
(TRIM/NR, pin 5). Figure 30 shows a typical circuit
that allows an output adjustment of ±15mV

10Hz and 20Hz. Such a filter decreases the overall
noise measured on the VOUT pin by half. Higher
capacitance results in a lower filter cutoff frequency,
further reducing output noise. Note that use of this
capacitor increases startup time.

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.

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)

IMPORTANT NOTICE
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, modifications, enhancements, improvements,
and other changes to its products and services at any time and to discontinue any product or service without notice. Customers should
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All products are
sold subject to TI’s terms and conditions of sale supplied at the time of order acknowledgment.
TI warrants performance of its hardware products to the specifications applicable at the time of sale in accordance with TI’s standard
warranty. Testing and other quality control techniques are used to the extent TI deems necessary to support this warranty. Except where
mandated by government requirements, testing of all parameters of each product is not necessarily performed.
TI assumes no liability for applications assistance or customer product design. Customers are responsible for their products and
applications using TI components. To minimize the risks associated with customer products and applications, customers should provide
adequate design and operating safeguards.
TI does not warrant or represent that any license, either express or implied, is granted under any TI patent right, copyright, mask work right,
or other TI intellectual property right relating to any combination, machine, or process in which TI products or services are used. Information
published by TI regarding third-party products or services does not constitute a license from TI 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 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. Reproduction of this information with alteration is an unfair and deceptive
business practice. TI is not responsible or liable for such altered documentation. Information of third parties may be subject to additional
restrictions.
Resale of TI products or services with statements different from or beyond the parameters stated by TI for that product or service voids all
express and any implied warranties for the associated TI product or service and is an unfair and deceptive business practice. TI is not
responsible or liable for any such statements.
TI products are not authorized for use in safety-critical applications (such as life support) where a failure of the TI product would reasonably
be expected to cause severe personal injury or death, unless officers of the parties have executed an agreement specifically governing
such use. Buyers represent that they have all necessary expertise in the safety and regulatory ramifications of their applications, and
acknowledge and agree that they are solely responsible for all legal, regulatory and safety-related requirements concerning their products
and any use of TI products in such safety-critical applications, notwithstanding any applications-related information or support that may be
provided by TI. Further, Buyers must fully indemnify TI and its representatives against any damages arising out of the use of TI products in
such safety-critical applications.
TI products are neither designed nor intended for use in military/aerospace applications or environments unless the TI products are
specifically designated by TI as military-grade or "enhanced plastic." Only products designated by TI as military-grade meet military
specifications. Buyers acknowledge and agree that any such use of TI products which TI has not designated as military-grade is solely at
the Buyer's risk, and that they are solely responsible for compliance with all legal and regulatory requirements in connection with such use.
TI products are neither designed nor intended for use in automotive applications or environments unless the specific TI products are
designated by TI as compliant with ISO/TS 16949 requirements. Buyers acknowledge and agree that, if they use any non-designated
products in automotive applications, TI will not be responsible for any failure to meet such requirements.
