Features
Description
The TS431 is a low-voltage, three-terminal,
programmable shunt voltage reference.
The output voltage can be set to any value
between V
resistors.
The TS431 is able to operate at a lower voltage
(1.24V) and lower cathode current than the widely
used TL431 and TL1431 shunt voltage reference.
1. Qualified and characterized according to AEC Q100 and Q003 or equivalent, advanced screening according to AEC Q001
