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.
