ADR01, ADR02, and ADR03 are component-level compatible with REF01,
REF02, and REF03, respectively. No guarantees for system-level compatibility
are implied. SOIC-8 versions of ADR01/ADR02/ADR03 are pin-to-pin
compatible with SOIC-8 versions of REF01/REF02/REF03, respectively, with
the additional temperature monitoring function.

GENERAL DESCRIPTION
The ADR01, ADR02, ADR03, and ADR06 are precision 10 V,
5 V, 2.5 V, and 3.0 V band gap voltage references featuring high
accuracy, high stability, and low power. The parts are housed in
tiny SC70-5 and TSOT-5 packages, as well as the SOIC-8
versions. The SOIC-8 versions of the ADR01, ADR02, and
ADR03 are drop-in replacements
1
to the industry-standard
REF01, REF02, and REF03. The small footprint and wide
operating range make the ADR0x references ideally suited for
general-purpose and space-constraint 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 provided on the devices
for fine adjustment of the output voltage.
The ADR01, ADR02, ADR03, and ADR06 are compact, low drift
voltage references that provide an extremely stable output
voltage from a wide supply voltage range. They are available in
SC70-5, TSOT-5, and SOIC-8 packages with A and B grade
selections. All parts are specified over the extended industrial
(–40°C to +125°C) temperature range.
