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
