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 looppowered
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.
