REF3040 (ACTIVE) 4.096V 50ppm/Degrees C, 50uA in SOT23-3 Series (Bandgap) Voltage Reference

 

Description

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.
