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.
Features
Excellent temperature characteristic of Vref :
50ppm/
°C (typ)
Output voltage settable : Approximately 2.5V to 36V.
Output flow-in current range : 1mA to 100mA
Low dynamic resistance : 0.15
(typ)
Fast response.
Low output noise voltage.
Small-sized TO-92.
