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
V
REF
(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.
