  • The TS821 is a low power shunt voltage reference providing a stable 1.225V output voltage over the industrial temperature range (-40°C to +85°C). Availabe in SOT23-3 surface mount package, it can be designed in applications where space saving is critical.

    The low operating current is a key advantage for power restricted designs. In addition, the TS821 is very stable and can be used in a broad range of application conditions.

    Key Features

    • 120ppm/°C maximum temperature coefficient
    • 1.225V typical output voltage
    • High precision @ 25°C+/- 2% (standard version)+/- 1% (A grade)+/- 0.5% (B grade)
    • Ultra low operating current: 45μA maximum at 25°C
    • Industrial temperature range: -40°C to +85°C
    • High stability when used with capacitive loads
