The REF31xx-Q1 is a family of precision, low power, low dropout, series voltage references available in the tiny 3-pin SOT-23 package.

The REF31xx-Q1 small size and low power consumption (100µA typical) make it suitable for portable and battery-powered applications. The REF31xx-Q1 does not require a load capacitor and can sink or source up to 10mA of output current.

Unloaded, the REF31xx-Q1 can operate on supplies down to 5mV above the output voltage. All models are specified for the wide temperature range of –40°C to +125°C.
