Output voltage can be set to any value between VREF (1.24 V) and 18 V with two external resistors (see Figure 2). These devices operate from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.

They have a typical output impedance of 0.25 Ω. Active output circuitry provides a very sharp turn-on characteristic, making the TLVH431 and TLVH432 excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies. The TLVH432 is identical to the TLVH431, but is offered with different pinouts for the SOT-23-3 and SOT-89 packages. 2 TLVH431, TLVH431A, TLVH431B TLVH432, TLVH432A, TLVH432B LOW-VOLTAGE ADJUSTABLE PRECISION SHUNT REGULATORS www.ti.com SLVS555F – NOVEMBER 2004 – REVISED OCTOBER 2005 ORDERING INFORMATION TA VREF TOLERANCE PACKAGE (1) SC-70 – DCK SOT-23-5 – DBV Reel of 3000 TLVH431BCDCKR Reel of 250 TLVH431BCDCKT Reel of 3000 TLVH431BCDBVR Reel of 250 TLVH431BCDBVT Reel of 3000 0.5% SOT-23-3 – DBZ Reel of 250 SOT-89 – PK TO-92 – LP SC-70 – DCK SOT-23-5 – DBV Reel of 1000 1% SOT-89 – PK TO-92 – LP SC-70 – DCK SOT-23-5 – DBV (1) (2) Y2H_ TLVH431BCPK V7 TLVH432BCPK VN Reel of 250 TLVH431ACDCKT Reel of 3000 TLVH431ACDBVR Reel of 250 TLVH431ACDBVT YP_ Y3P_ Y3P_ TLVH432ACDBZR Y2E_ TLVH431ACDBZT Y3P_ TLVH432ACDBZT Y2E_ TLVH431ACPK W2 TLVH432ACPK VK TLVH431ACLP Reel of 2000 TLVH431ACLPR Reel of 3000 TLVH431CDCKR Reel of 250 TLVH431CDCKT Reel of 3000 TLVH431CDBVR Reel of 250 TLVH431CDBVT Reel of 1000 ZA431B TLVH431ACDBZR Bulk of 1000 Reel of 250 TO-92 – LP Y3J_ TLVH432BCDBZT TLVH431ACDCKR SOT-23-3 – DBZ SOT-89 – PK TLVH431BCDBZT Reel of 3000 Reel of 3000 1.5% Y2H_ TLVH431BCLPR Reel of 1000 Y3J_ Y3J_ TLVH431BCLP Reel of 250 YH_ TLVH432BCDBZR Reel of 2000 SOT-23-3 – DBZ TOP-SIDE MARKING (2) TLVH431BCDBZR Bulk of 1000 Reel of 3000 0°C to 70°C ORDERABLE PART NUMBER ZA431A YU_ Y3U_ TLVH431CDBZR Y3U_ TLVH432CDBZR Y2A_ TLVH431CDBZT Y3U_ TLVH432CDBZT Y2A_ TLVH431CPK W4 TLVH432CPK VG Bulk of 1000 TLVH431CLP Reel of 2000 TLVH431CLPR ZA431 Package drawings, standard packing quantities, thermal data, symbolization, and PCB design guidelines are available at www.ti.com/sc/package.

Flyback With Isolation Using TLVH431 and TLVH432 as Voltage Reference and Error Amplifier Figure 18 shows the TLVH431 used in a 3.3-V isolated flyback supply. Output voltage VO can be as low as reference voltage VREF (1.24 V). The output of the regulator plus the forward voltage drop of the optocoupler LED (1.24 + 1.4 = 2.64 V) determine the minimum voltage that can be regulated in an isolated supply configuration. Regulated voltage as low as 2.7 Vdc is possible in the topology shown in Figure 18. 21 PACKAGE OPTION ADDENDUM www.ti.com 4-Nov-2005 PACKAGING INFORMATION Orderable Device Status (1) Package Type

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) 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. 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.
