3 Description
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 (100 μA typical) make it ideal for
portable and battery-powered applications. The
REF31xx-Q1 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-Q1 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.
