KTP (PowerFLEX /TO-252) PACKAGE (TOP VIEW) CATHODE ANODE REF DESCRIPTION/ORDERING INFORMATION The TL431 and TL432 are three-terminal adjustable shunt regulators, with specified thermal stability over applicable automotive, commercial, and military temperature ranges. The output voltage can be set to any value between Vref (approximately 2.5 V) and 36 V, with two external resistors (see Figure 17). These devices have a typical output impedance of 0.2 Ω. Active output circuitry provides a very sharp turn-on characteristic, making these devices excellent replacements for Zener diodes in many applications, such as onboard regulation, adjustable power supplies, and switching power supplies. The TL432 has exactly the same functionality and electrical specifications as the TL431, but has different pinouts for the DBV, DBZ, and PK packages. Both the TL431 and TL432 devices are offered in three grades, with initial tolerances (at 25°C) of 0.5%, 1%, and 2%, for the B, A, and standard grade, respectively. In addition, low output drift vs temperature ensures good stability over the entire temperature range. The TL43xxC devices are characterized for operation from 0°C to 70°C, the TL43xxI devices are characterized for operation from –40°C to 85°C, and the TL43xxQ devices are characterized for operation from –40°C to 125°C. 2 Submit Documentation Feedback Copyright © 2004–2011, Texas Instruments Incorporated Product Folder Link(s): TL431 TL431A TL431B TL432 TL432A TL432B TL431, TL431A, TL431B TL432, TL432A, TL432B SLVS543L – AUGUST 2004 – REVISED FEBRUARY 2011 www.ti.com Vref TOLERANCE (25°C) = 2% TL431, TL432 ORDERING INFORMATION (1) PACKAGE (2) TA PDIP (P) SOIC (D) SOP (PS) SOT-23-5 (DBV) 0°C to 70°C SOT-23-3 (DBZ) SOT-89 (PK) TO-226/TO-92 (LP) TSSOP (PW) PDIP (P) SOIC (D) SOT-23-5 (DBV) -40°C to 85°C SOT-23-3 (DBZ) SOT-89 (PK) TO-226/TO-92 (LP) (1) (2) (3) Tube of 50 TL431CP Tube of 75 TL431CD Reel of 2500 TL431CDR Reel of 2000 TL431CPSR Reel of 3000 TL431CDBVR Reel of 250 TL431CDBVT Reel of 3000 TL432CDBVR Reel of 250 TL432CDBVT Reel of 3000 TL431CDBZR Reel of 250 TL431CDBZT Reel of 3000 TL432CDBZR Reel of 250 TL432CDBZT Reel of 1000 TL431CP TL431C T431 T3C_ T4C_ T3C_ T4C_ TL431CPK 43 TL432CPK 2A Bulk of 1000, straight lead TL431CLP Ammo of 2000, formed lead TL431CLPM Reel of 2000, formed lead TL431CLPR Tube of 150 TL431CPW Reel of 2000 TL431CPWR Tube of 50 TL431IP Tube of 75 TL431ID Reel of 2500 TL431IDR Reel of 3000 TL431IDBVR Reel of 250 TL431IDBVT Reel of 3000 TL432IDBVR Reel of 250 TL432IDBVT Reel of 3000 TL431IDBZR Reel of 250 TL431IDBZT Reel of 3000 TL432IDBZR Reel of 250 TL432IDBZT Reel of 1000 TOP-SIDE MARKING (3) ORDERABLE PART NUMBER TL431C T431 TL431IP TL431I T3I_ T4I_ T3I_ T4I_ TL431IPK 3I TL432IPK 2B Bulk of 1000, straight lead TL431ILP Ammo of 2000, formed lead TL431ILPM Reel of 2000, formed lead TL431ILPR TL431I For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI web site at www.ti.com.

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. Addendum-Page 18 PACKAGE OPTION ADDENDUM www.ti.com 20-Aug-2011 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) (3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.
