DESCRIPTION/ORDERING INFORMATION
The TLVH431 and TLVH432 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 2). These devices operate from a lower
voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.
When used with an optocoupler, the TLVH431 and TLVH432 are ideal voltage references in isolated feedback
circuits for 3-V to 3.3-V switching-mode power supplies. They have a typical output impedance of 0.25
. 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.
