Description
The TS4040 is a low power shunt voltage
reference providing a stable 2.5V output voltage
over the industrial temperature range (-40°C to
+85°C). Available in SOT23-3 surface mount
package, it can be designed in applications where
space saving is critical.
The low operating current is a key advantage for
power restricted designs. In addition, the TS4040
is very stable and can be used in a broad range of
application conditions.
