ST432

ST432 Adjustable Precision Shunt Regulator DESCRIPTION ST432 is low-voltage three-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 (1.24V) and 20V with two external resistors. These devices have a typical output impedance of 0.25Ω. Active output circuitry provides a very sharp turn-on characteristic, making the ST432 excellent replacements for low-voltage Zener diodes in many applications, including onboard regulation and adjustable power supplies.
