REF3225 (ACTIVE)

2.5V 4ppm/Degrees C, 100uA SOT23-6 Series (Bandgap) Voltage Reference

 

Recommended alternative parts

  • REF2125  -  The REF2125 precision series reference offers clean-start functionality for safety-critical applications
  • REF3425  -  The REF3425 precision series reference offers lower temperature drift, Iq, and noise

Description

The REF32xx is a very low drift, micropower, low-dropout, precision voltage reference family available in the tiny SOT23-6 package.

The small size and low power consumption (120&micr;A max) of the REF32xx make it ideal for portable and battery-powered applications. This reference is stable with any capacitive load.

The REF32xx can be operated from a supply as low as 5mV above the output voltage, under no load conditions. All models are specified for the wide temperature range of –40°C to +125°C.

Features

  • Excellent Specified Drift Performance:
    • 7ppm/°C (max) at 0°C to +125°C
    • 20ppm/°C (max) at –40°C to +125°C
  • Microsize Package: SOT23-6
  • High Output Current: ±10mA
  • High Accuracy: 0.01%
  • Low Quiescent Current: 100µA
  • Low Dropout: 5mV
