Description
The TS4041 is a low power shunt voltage
reference providing a stable 1.225V output
voltage over the industrial temperature range
(-40°C to +85°C). Availabe 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 TS4041
is very stable and can be used in a broad range of
application conditions.
