Monolithic Linear IC
L5431
High-Precision Variable Shunt
Voltage Regulator
Overview
The L5431 is a high-precision variable shunt voltage regu-
lator IC whose output voltage can be set to a value from
approximately 2.5V to 36V by using external resistors.
Because of low output resistance and fast pulse response,
the L5431 can be most suitably used as high-precision volt-
age reference, high-speed comparator, or zener diode.
