Product Summary

The REF03G is a precision voltage reference which provides a stable 2.5 V output, with minimal change for variations in supply voltage, ambient temperature, or loading conditions. Single-supply operation over an input voltage range of 4.5 V to 33 V with a current drain of 1 mA and good temperature stability is achieved using an improved band gap design. Primarily targeted at price sensitive applications, the REF03 is available in plastic mini DIPs and surface-mount small outline plastic packages. For improved performance or -40℃ to +125℃ operation, see the ADR03 data sheet.
