TS4040 2.5V micropower shunt voltage reference Features ■ ■ ■ ■ ■ ■ 2.5V output voltage Ultra low current consumption: 40A typ. High precision @ 25°C: ±2% and ±1% High stability when used with capacitive loads Industrial temperature range:-40°C to +85°C 150ppm/°C maximum temperature coefficient L SOT23-3L (Plastic micropackage) Applications ■ ■ ■ ■ ■ Computers Instrumentation Battery chargers Switch mode power supply Battery operated equipments Pin connections (Top view) Description The TS4040 is a low power shunt voltage reference providing a stable 2.5V output voltage over the industrial temperature range (-40°C to +85°C). Available 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 TS4040 is very stable and can be used in a broad range of application conditions.
