DESCRIPTION

The REF31xx is a family of precision, low power, low dropout, series voltage references available in the tiny SOT23-3 pack- age. The REF31xx’s small size and low power consumption (100µA typ) make it ideal for portable and battery-powered applications. The REF31xx does not require a load capacitor, but is stable with any capacitive load and can sink/source up to 10mA of output current. Unloaded, the REF31xx can be operated on supplies down to 5mV above the output voltage. All models are specified for the wide temperature range of –40°C to +125°C.

ELECTRICAL CHARACTERISTICS

Boldface limits apply over the specified temperature range, TA = –40°C to +125°C. At TA = +25°C, ILOAD = 0mA, VIN = 5V, unless otherwise noted. REF31xx PARAMETER CONDITIONS MIN TYP MAX UNITS ELECTROSTATIC DISCHARGE SENSITIVITY This integrated circuit can be damaged by ESD. Texas Instru- ments recommends that all integrated circuits be handled with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage. ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.
