Description
The TL1431 is a programmable shunt voltage
reference with guaranteed temperature stability
over the entire operating temperature range.
The output voltage may be set to any value
between 2.5 V and 36 V with two external
resistors.
The TL1431 operates with a wide current range
from 1 to 100 mA with a typical dynamic
impedance of 0.2 Ω.
