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
