ST432 2007. V1

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.
