3 Description

The REF33xx is a low-power, precision, low-dropout

voltage reference family available in tiny SC70-3 and

SOT-23-3 packages, and in a 1.5-mm × 1.5-mm

UQFN-8 package. Small size and low power

consumption (5-μA max) make the REF33xx ideal for

a wide variety of portable and battery-powered

applications.

The REF33xx can be operated at a supply voltage

180 mV above the specified output voltage under

normal load conditions, with the exception of the

REF3312, which has a minimum supply voltage of

1.7 V. All models are specified for the wide

temperature range of –40°C to +125°C.
