DESCRIPTION/ORDERING INFORMATION
The TL4050 series of shunt voltage references are versatile easy-to-use references suitable for a wide array of
applications. The two-terminal fixed-output 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 TL4050 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 mA (typ), the TL4050 also is ideal for portable applications.
The TL4050xI is characterized for operation over an ambient temperature range of –40°C to 85°C. The
TL4050xQ is characterized for operation over an ambient temperature range of –40°C to 125°C.

(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), qJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/qJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

Figure 1. Start-Up Test Circuit
Output Capacitor
The TL4050 does not require an output capacitor across cathode and anode for stability. However, if an output
bypass capacitor is desired, the TL4050 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.
Use With ADCs or DACs
The TL4050x-41 is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition
systems. For 12-bit systems operating from 5-V supplies, such as the ADS7842 (see Figure 2), the TL4050x-41
(4.096 V) permits operation with an LSB of 1 mV.

Cathode and Load Currents
In a typical shunt-regulator configuration (see Figure 3), an external resistor, RS, is connected between the
supply and the cathode of the TL4050. RS must be set properly, as it sets the total current available to supply the
load (IL) and bias the TL4050 (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-rated value of 15 mA.
RS is calculated according to Equation 1:

(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)
