TS4041 1.225V MICROPOWER SHUNT VOLTAGE REFERENCE ■ 1.225V TYP 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 to +85°C ■ 150ppm/°C MAXIMUM TEMPERATURE COEFFICIENT Z TO92 (Plastic Package) DESCRIPTION The TS4041 is a low power shunt voltage reference providing a stable 1.225V 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 TS4041 is very stable and can be used in a broad range of application conditions.
