SBVS032E – MARCH 2002 – REVISED MARCH 2004 www.ti.com

DESCRIPTION

The REF30xx is a precision, low power, low voltage dropout voltage reference family available in a tiny SOT23-3. The REF30xx small size and low power consumption (50µA max) make it ideal for portable and battery-powered applica- tions. The REF30xx does not require a load capacitor, but is stable with any capacitive load. Unloaded, the REF30xx can be operated with supplies within 1mV of output voltage. All models are specified for the wide temperature range, –40°C to +125°C.

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.
