20ppm/°C Max, 100µA, SOT23-3 Series Voltage Reference - REF3112

REF3112 (ACTIVE)

20ppm/°C Max, 100µA, SOT23-3 Series Voltage Reference

 

Description

The REF31xx is a family of precision, low power, low dropout, series voltage references available in the tiny 3-pin SOT-23 package.

The REF31xx’s small size and low power consumption (100 µA typical) make it ideal for portable and battery-powered applications. The REF31xx does not require a load capacitor, but is stable with any capacitive load and can sink or source up to 10 mA of output current.

Unloaded, the REF31xx can operate on supplies down to 5 mV above the output voltage. All models are specified for the wide temperature range of –40°C to +125°C.

Features

  • Size Package: SOT23-3
  • Low Dropout: 5 mV
  • High Output Current: ±10 mA
  • High Accuracy: 0.2% Maximum
  • Low IQ: 115 µA Maximum
  • Excellent Specified Drift Performance:
    • 15 ppm/°C (Maximum) from 0°C to +70°C
    • 20 ppm/°C (Maximum) from –40°C to +125°C
