TS4041

TS4041 1.225V micropower shunt voltage reference Features ■ 1.225V typical output voltage ■ Ultra low operating current: 65µA maximum at 25°C ■ High precision @ 25°C – +/- 2% – +/- 1% – +/- 0.5% ■ High stability when used with capacitive loads ■ Industrial temperature range: -40°C to +85°C ■ 150ppm/°C maximum temperature coefficient Application ■ Computers ■ Instrumentation ■ Battery chargers ■ Switch mode power supply ■ Battery operated equipments Description The TS4041 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 TS4041 is very stable and can be used in a broad range of application conditions.
