Cathode 2 Description SOT23-3
The TS3431 is a programmable shunt voltage (top view) 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. Available in SOT23-3 surface mount package, it can be used in application designs where space saving is critical.
