The TLVH431 and TLVH432 devices are low-voltage 3-terminal adjustable voltage references, with specified thermal stability over applicable industrial and commercial temperature ranges. Output voltage can be set to any value between VREF (1.24 V) and 18 V with two external resistors (see Figure 19). These devices operate from a lower voltage (1.24 V) than the widely used TL431 and TL1431 shuntregulator references. When used with an optocoupler, the TLVH431 and TLVH432 devices are ideal voltage references in isolated feedback circuits for 3-V to 3.3-V switchingmode power supplies. 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 devices excellent replacements for low-voltage Zener diodes in many applications, including on-board regulation and adjustable power supplies. The TLVH432 device is identical to the TLVH431 device, but is offered with different pinouts for the 3-pin SOT-23 and SOT-89 packages.
