Data-Acquisition Systems Power Supplies and Power-Supply Monitors Instrumentation and Test Equipment Process Controls Precision Audio Automotive Electronics Energy Management Battery-Powered Equipment DCK (SC-70) PACKAGE (TOP VIEW) ANODE NC CATHODE 1 5 NC 4 NC 2 3 NC – No internal connection 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 µA (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 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

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.

SLOS486A – JUNE 2007 – REVISED AUGUST 2009 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: ǒVS * VZǓ RS + (I L ) I Z) (1) VS RS IZ + IL IL VZ IZ TL4050 Figure 3.
