REF3312

30ppm/C 漂移、3.9uA、SOT23-3、SC70-3 电压基准

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 , 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.
