Description

The REF31xx is a family of precision, low power, low dropout, series voltage references available in the tiny SOT23-3 package.

The REF31xx’s small size and low power consumption (100µA typ) 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/source up to 10mA of output current.

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