Hot-selling and scarce REF3333AIDBZR Series Voltage Reference IC Fixed 3.3V V ±0.15% 5 mA SOT-23-3 spot stock
REF3333AIDBZR Series Voltage Reference IC Fixed 3.3V V ±0.15% 5 mA SOT-23-3 spot stock
Product Descriptions
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 (5μA max) make the REF33xx ideal for a wide variety of portable and battery-powered applications.
The REF33xx can be operated at a supply voltage180mV above the specified output voltage under normal load conditions, with the exception of the REF3312, which has a minimum supply voltage of1.8V. All models are specified for the wide temperature range, –40°C to +125°C.
