3 Description

The REF35-Q1 is a family of nanopower, low-drift,

high-precision series reference devices. The REF35-

Q1 family features ±0.05 initial accuracy with

typical 650 nA power consumption. The temperature

coefficient (15 ppm/ºC) and long-term stability (30

ppm at 1000 hours) of the device can help

improve system stability and reliability. The low

power consumption combined with high precision

specifications are designed for a wide variety of low

current applications.

The REF35-Q1 supplies up to 10 mA current with

3.3 ppmp-p noise and 20 ppm/mA load regulation.

With this feature set, REF35-Q1 creates a strong

low-noise, high accuracy power supply for precision

sensors and 12–16b data converters.

The family is fully specified for operation from -40°C to

125°C and is functional over -55°C to 125°C.

The REF35-Q1 is available in wide output voltage

variants starting from 1.20 V to 5.0 V. The device

is offered in space saving SOT23-6 pin package.
