DESCRIPTION
The TS4040 is a low power shunt voltage reference providing a stable 2.5V output voltage over
the industrial temperature range (-40 to +85°C).
Available in SOT23-3 s urface 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 add ition, the TS40 40
is very stable and can be used in a broad range of
application conditions.
APPLICATION
■ Computers
■ Instrumentation
■ Battery chargers
■ Switch Mode Power Supply
■ Battery operated equipments
