DESCRIPTION
The TS2431 is a programmable shunt voltage
reference with guaranteed temperature stability
over the entire temperature range of operation
(-40 to +105°C). The output voltage may be set to
any value between 2.5V 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.
