DESCRIPTIONThe TS822isalow power shunt voltage reference
providinga stable 2.5V output voltage overthein-
dustrial temperature range (-40to +85°C). Avail-
abein SOT23-3 surface mount package,it canbe
designedin applications where space savingisa
critical issue.
The low operating currentisa key advantagefor
power restricted designs.In addition,the TS822is
very stable and canbe usedina broad rangeof
application conditions.
