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.
