REF3040AIDBZR

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 looppowered industrial applications such as pressure and
temperature transmitter applications. The REF30xx
is easy to use in intrinsically safe and explosionproof 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 batterypowered applications.
