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

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.
