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.
