• microSize Package: SOT-23-3
voltage, reference family available in a tiny SOT-23-3
• Low Dropout: 1 mV
package. The REF30xx offers excellent temperature
• High Output Current: 25 mA
drift and initial accuracy while operating at a
quiescent current of 42 µA (typ).
• High Accuracy: 0.2%
• Low I
Q
: 42 µA (typ)
The low power consumption and the relatively high
precision make the REF30xx very attractive for loop-
• Excellent Specified Drift Performance:
powered industrial applications such as pressure and
– 50 ppm/°C (max) from 0°C to 70°C
temperature transmitter applications. The REF30xx is
– 75 ppm/°C (max) from –40°C to +125°C
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
• Temperature and Pressure Transmitters
to +125°C.
• Portable, Battery-powered Equipment
The REF30xx operates with supplies within 1 mV of

dropout along with small size and low power
consumption make The REF30xx ideal for portable
• Handheld Test Equipment
and battery-powered applications.
