DESCRIPTION
The TS4041 is a low power shunt voltage
reference providing a stable 1.225V output
voltage over the industrial temperature range (-40
to +85°C). Availabe in SOT23-3 surface mount
package, it can be designed in applications where
space saving is a critical issue.
The low operating current is a key advantage for
power restricted designs. In addition, the TS4041
is very stable and can be used in a broad range of
application conditions.
