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.
