Description for the REF3312

The REF33xx is a low-power, precision, low-dropout voltage reference family available intiny SC70-3 and SOT-23-3 packages, and in a 1.5-mm × 1.5-mm UQFN-8 package. Small size and lowpower consumption (5-µA max) make the REF33xx ideal for a wide variety of portable andbattery-powered applications.

The REF33xx can be operated at a supply voltage 180 mV above the specified output voltageunder normal load conditions, with the exception of the REF3312, which has a minimum supply voltageof 1.7 V. Allmodels are specified for the wide temperature range of –40°C to +125°C.
