Product Overview
LM4040DECT-2.5 is a low power and high accuracy shunt voltage reference in 5 pin SOT323 package. It provides a stable output voltage over the industrial temperature range (-40 to +125°C), with a maximum temperature coefficient of 70ppm/°C. The very low operating current is a key advantage for power restricted designs. The LM4040 is very stable and can be used in a broad range of application conditions. Typical applications include portable, battery-operated equipment, data acquisition system and instrumentation.
- Output voltage is 2.5V
- Ultra low operating current of 10µA at 25°C
- High precision of +/- 1% at 25°C
- Stable when used with capacitive loads
