Voltage references are 40% smaller than
SOT23
Low-power voltage references feature high accuracy (+/-0.15% maximum) and low temperature drift (30ppm/C maximum) in a SC70-3 package.
Texas Instruments has introduced a family of low-power (5uA), series voltage references featuring high accuracy (+/-0.15% maximum) and low temperature drift (30ppm/C maximum) in a SC70-3 package - 40% smaller than a SOT23 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

RF platform brings three radios together
Texas Instruments has developed the industry's first solution that integrates mobile WLAN (mWLAN), Bluetooth and FM stereo audio all in a space-saving platform for mobile phones.
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 minimises system error over temperature.
Additionally, the low dropout voltage of 110mV (typical at 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 -40 to +125C.
The six versions of the REF33xx family are available now in SOT23-3 and SC70-3 packages from TI and its authorised distributors.
The devices are priced at US $0.85 in 1000-piece quantities (suggested resale pricing).
