Description
The TS3431 is a programmable shunt voltage
reference with guaranteed temperature stability
over the entire operating temperature range
(-40°C to +125°C). The output voltage can be set
to any value between 1.24V and 24V with an
external resistor bridge.
Available in SOT23-3 surface mount package, it
can be used in application designs where space
saving is critical.
