DESCRIPTION

The TS822 is a low power shunt voltage reference

providing a stable 2.5V output voltage over the in-

dustrial temperature range (-40 to +85°C). Avail-

abe 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 TS822 is

very stable and can be used in a broad range of

application conditions.
