The REF30xx is a precision,
low-power, low-dropout voltage, reference family available in a tiny 3-pin SOT-23 package. The
REF30xx offers excellent temperature drift and initial accuracy while operating at a quiescent
current of 42 µA (typical).
The low power consumption and the relatively high precision make the REF30xx very
attractive for loop-powered industrial applications such as pressure and temperature transmitter
applications. The REF30xx is easy to use in intrinsically safe and explosion-proof applications
because it does not require a load capacitor to be stable. The REF30xx is specified over the
extended industrial temperature range of –40°C to +125°C.
The REF30xx operates with supplies within 1 mV of output voltage under zero-load
conditions. Engineers can use the low dropout, small size, and low power consumption of the REF30xx
in portable and battery-powered applications.
