GENERAL DESCRIPTION

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 PDIPs and surface-mount small outline plastic

packages. For improved performance or −40°C to +125°C

operation, see the

Rev. G
