20ppm/°C Max, 100µA Series Voltage Reference



The REF3140 is a precision, low power, low dropout, series voltage reference.

The REF3140’s small size and low power consumption make it ideal for portable and battery-powered applications. The REF3140 does not require a load capacitor, but is stable with any capacitive load and can sink/source up to 10mA of output current.

Unloaded, the REF3140 can be operated on supplies down to 5 mV above the output voltage.


  • Low Dropout
  • High Output Current
  • High Accuracy
