SP431
High
Voltage Adjustable Precision Shunt Regulators
DESCRIPTION The SP431 is high-
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 (2.
5V) and 36V 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 SP431 excellent replacements for low-
voltage Zener diodes in many applications, including onboard regulation and adjustable power supplies.
