DESCRIPTION

The TS822 is a low power shunt voltage reference
providing a stable 2.5V 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 restricteddesigns. In addition, the TS822 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
