Automotive voltage reference is ideal for portable and battery-powered applications

The REF31xx-Q1 is a family of precision, low power, low dropout, series voltage references available in the tiny three-pin SOT-23 package from Texas Instruments. The device’s small size and low power consumption (100µA typical) make it ideal for portable and battery-powered applications. It does not require a load capacitor, but is stable with any capacitive load and can sink or source up to 10 mA of output current. Unloaded, the device can operate on supplies down to 5mV above the output voltage. All models are specified for the wide temperature range of –40C to +125C.
