TI Introduces the Low-Power Series Voltage Reference Family

REF3312 - The Smallest in a Tiny SC70-3 Package

TI Image The REF33xx is the newest product in the voltage reference product line combining the micro-sized SC70 package with low 5µA quiescent current for battery powered and handheld applications. This is the LOWEST POWER series voltage reference in the SC70-3 package. Its small size, robust output drive, and low dropout voltage make this a value leader for applications requiring low power and a small footprint.

The REF33xx family of voltage references offers the combination of low power consumption and micro-sized packaging. As the industry's lowest power series voltage reference in the SC70 3-pin micro-sized package, it delivers high initial accuracy and low temperature drift across the extended industrial temperature range. The SC70 package saves designers ~40% board area over the SOT23 package. This allows systems to have a smaller footprint or increases component density. The super-low dropout voltage allows a wide range of supply voltages, as well as improving performance in battery based systems as battery voltage decreases with use.
