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.
This datasheet describes the TS3431 reference voltage IC supplied in an ECOPACK® SOT23‑3L package. It includes a block diagram, absolute maximum ratings, operating conditions, and detailed electrical characteristics such as reference voltage, current and temperature coefficients.
Additional sections cover package mechanical data, ordering codes, revision history and legal notices. The document is intended for designers who need precise specifications for circuit integration and for procurement teams selecting the correct part number.
