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

voltage (1.24 V) than the widely used TL431 and TL1431 shunt-regulator references.
