3 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.
