TS3431 ■ Cathode 3 Anode 2 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 1.24 V and 24 V with an
external resistor bridge. SOT23-3
(top view) Available in SOT23-3 surface mount package, it
can be used in application designs where space
saving is critical. August 2012
