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.
