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 restricted designs. 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
