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 and DBZ 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 POST OFFICE BOX 655303 • DALLAS, TEXAS 75265 SLVS543A – AUGUST 2004 − REVISED AUGUST 2004 description/ordering information (continued) Vref TOLERANCE (25°C) = 2% TL431, TL432 ORDERING INFORMATION ORDERABLE PART NUMBER PACKAGE† 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) 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 TL431CPK Bulk of 1000 TL431CLP Ammo of 2000 TL431CLPM Reel of 2000 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 TL431IPK Bulk of 1000 TL431ILP Reel of 2000 TL431ILPR TOP-SIDE MARKING‡ TL431CP TL431C T431 T3C_ TAB_ TAC_ TAB_ 43 TL431C T431 TL431IP TL431I T3I_ T4A_ TAI_ T4A_ 3I TL431I † Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package. ‡ DBV/DBZ: The actual top-side marking has one additional character that designates the assembly/test site.
