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.

Microsize Packages: SC70-3, SOT-23-3, UQFN-8
Low Supply Current: 3.9 µA (typ)
Extremely Low Dropout Voltage: 110 mV (typ)
High Output Current: ±5 mA
Low Temperature Drift: 30 ppm/°C (max)
High Initial Accuracy: ±0.15% (max)
0.1-Hz to 10-Hz Noise: 35 µV_PP (REF3312)
Voltage Options: 1.2 V, 1.8 V, 2.5 V, 3 V, 3.3 V
