REF3325 30ppm/C 漂移、3.9uA、SOT23-3、SC70-3 电压基准
REF3325 描述
The REF33xx is a low-power, precision, low-dropout voltage reference family available in the tiny SC70-3 and SOT23-3 packages. Small size and low power consumption (5uA max) make the REF33xx ideal for a wide variety of portable and battery-powered applications.
The REF33xx can be operated at a supply voltage 180mV above the specified output voltage under normal load conditions, with the exception of the REF3325, which has a minimum supply voltage of 1.8V. All models are specified for the wide temperature range, -40°C to +125°C.
