LM4040
Features - Fixed 2.048 V, 2.5 V, 3.0 V, 4.096 V and 5.0 V output voltages - Ultra low operating current: 10 µA at 25 °C - High precision @ 25 °C: +/- 0.1% (LM4040A), +/- 0.2% (LM4040B), +/- 0.5 % (LM4040C), +/- 1% (LM4040D) - Very low LF noise: typ.10 µ Vp-p - Stable when used with capacitive loads - Industrial (-40 to +125 °C) temperature range - 70 ppm/°C max. temperature coefficient - Available in SOT23-3L and SOT323-5L packages Applications - Portable, battery-operated equipment - Data acquisition systems - Instrumentation Description The LM4040 is a low power and high accuracy shunt voltage reference providing a stable output voltage over the industrial temperature range (-40 to +125 °C), with a maximum temperature coefficient of 70 ppm/°C. It is available in 0.1%, 0.2%, 0.5% and 1% initial accuracy versions. The SOT323-5L and SOT23-3L packages can be designed in applications where space saving is a critical issue. The very low operating current is a key advantage for power...
