The combination of micro-size packaging and low current consumption make the REF33xx family suitable for portable and battery-powered consumer applications, and its high accuracy and low temperature drift make it a good choice for medical equipment, handheld instrumentation, test equipment and data acquisition systems. （See www.ti.com/ref33xx-pr.） High initial accuracy, low noise （28uVpp/V output） and a robust output drive of +/-5mA enable precision, low power ADC （such as ADS1000 and ADS7866） and MSP430 applications. The low temperature drift minimizes system error over temperature. Additionally, the low dropout voltage of 110mV （typ, 25C） supports precision spot voltage regulation for battery-powered applications. The REF33xx family offers six output voltages: 1.25V （REF3312）, 1.8V （REF3318）, 2.048V （REF3320）, 2.5V （REF3325）, 3.0V （REF3330） and 3.3V （REF3333）. The devices can operate at a supply voltage 110mV above the output voltage under specified load conditions, except the REF3312 which requires a minimum supply voltage of 1.8V. All models in this family are designed for the wide industrial temperature range of -40C to 125C. Available Today The six versions of the REF33xx family are available now in SOT23-3 and SC70-3 packages from TI and its authorized distributors. The devices are priced at $0.85 in 1,000-piece quantities （suggested resale pricing）.[/color][/font]
