3 Description

The REF30 is a precision, low-power, low-dropout voltage, reference family available in a tiny 3-pin SOT-23 package. REF30E is the enhanced performance version of REF30 family which is designed for precision applications. The REF30E offers improved temperature drift and initial accuracy while operating at a lower quiescent current of 25µA.

The low power consumption and the improved precision make the REF30E very attractive for loop-powered industrial applications such as pressure and temperature transmitter and battery-powered applications. The REF30/REF30E is specified over the extended industrial temperature range of –40°C to +125°C. The REF30 is easy to use in intrinsically safe and explosion-proof applications because the REF30 does not require a load capacitor to be stable.
