Description
The TS821 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 TS821 is
very stable and can be used in a broad range of
application conditions.
