DESCRIPTION/ORDERING INFORMATION
The TL4051 series of shunt voltage references are versatile easy-to-use references suitable for a wide array of
applications. The device is available in a fixed 1.225-V output or an adjustable output whose voltage is
determined by an external resistor divider. The device requires no external capacitors for operation and is stable
with all capacitive loads. Additionally, the reference offers low dynamic impedance, low noise, and low
temperature coefficient to ensure a stable output voltage over a wide range of operating currents and
temperatures.
The TL4051 is offered in three initial tolerances, ranging from 0.1% (max) for the A grade to 0.5% (max) for the
C grade. Thus, a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for
their applications. Packaged in the space-saving SOT-23-3 and SC-70 packages and requiring a minimum
current of 45 µA (typ), the TL4051 also is ideal for portable applications.
The TL4051xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The
TL4051xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can affect reliability.
(3) The package thermal impedance is calculated in accordance with JESD 51-7.

Output Capacitor
The TL4051 does not require an output capacitor across CATHODE and ANODE for stability. However, if an
output bypass capacitor is desired, the TL4051 is designed to be stable with all capacitive loads.
SOT-23 Pin Connections
There is a parasitic Schottky diode connected between pins 2 and 3 of the SOT-23 packaged device. Thus,
pin 3 of the SOT-23 package must be left floating or connected to pin 2.

Adjustable Version
The adjustable version allows VZ to be set by a user-defined resistor divider. The output voltage, VZ, is set
according to the equation shown in Figure 3.

Figure 3. Adjustable Shunt Regulator
Cathode and Load Currents
In a typical shunt regulator configuration (see Figure 4), an external resistor, RS, is connected between the
supply and the cathode of the TL4051. RS must be set properly, as it sets the total current available to supply
the load (IL) and bias the TL4051 (IZ). In all cases, IZ must stay within a specified range for proper operation of
the reference. Taking into consideration one extreme in the variation of the load and supply voltage (maximum IL
and minimum VS), RS must be small enough to supply the minimum IZ required for operation of the regulator, as
given by data sheet parameters. At the other extreme, maximum VS and minimum IL, RS must be large enough
to limit IZ to less than its maximum recommended rating of 12 mA.
RS is calculated as shown in Equation 1.

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.
