GENERAL DESCRIPTION
The REF01/REF02/REF03 series of precision voltage references
provide a stable 10.0 V, 5.0 V, or 2.5 V output with minimal change
in response to variations in supply voltage, ambient temperature
or load conditions. The devices are available in 8-lead SOIC, PDIP,
CERDIP, and TO-99 packages, as well as 20-terminal LCC
packages (883 only), furthering the usability of the devices in
both standard and high stress applications.
With an external buffer and a simple resistor network, the
TEMP terminal can be used for temperature sensing and
approximation. A TRIM terminal is also provided on the
device for fine adjustment of the output voltage.
The small footprint, wide supply range, and application
versatility make the REF01/REF02/REF03 series of references
ideal for general-purpose and space-constrained applications.
Newer designs should use the ADR01/ADR02/ADR03/ADR06
series of references, which offer higher accuracy and temperature
