TS3431
1.24V Programmable Shunt Voltage Reference
■ Adjustable output voltage: 1.24 to 24V
■ Several precision @ 25°C
±2%, ±1%, ±0.5% and ±0.25%
■ Sink current capability: 0.4 to 100mA
■ Industrial temperature range: -40 to +125°C
■ Performances compatible with industry
standard TL431
Description
The TS3431 is a programmable shunt voltage
reference with guaranteed temperature stability
over the entire temperature range of operation
(-40 to +125°C). The output voltage may 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 designed in applications where space
saving is a critical issue.
Applications
■ Computers
■ Instrumentation
■ Battery chargers
■ Switch mode power supply
■ Battery operated equipments
