The REF03 precision voltage reference 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°C to +125°C operation, see the ADR03 data sheet.
