24 V adjustable shunt voltage reference 3 2 1 SOT23-3L (Plastic micropackage) Reference 1 Cathode 2 TS3431 3 Anode SOT23-3L (top view) Maturity status link TS3431 Features • Adjustable output voltage: 1.
24 to 24 V • Several precision levels @ 25 °C ± 2%, ± 1%, ± 0.
5% and ± 0.
25% • Sink current capability: 0.
4 to 100 mA • Industrial temperature range: - 40 °C to + 105 °C • Performance compatible with industry standard TL431 Applications • Computers • Instrumentation • Battery chargers • Switch mode power supply • Battery operated equipment Description The TS3431 is an adjustable 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.
Available in SOT23-3 surface mount package, it can be used in application designs where space saving is critical.
