The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V,
5.0 V, 2.5 V, and 3.0 V band gap voltage references featuring high
accuracy, high stability, and low power consumption. The parts
are housed in tiny, 5-lead SC70 and TSOT packages, as well as
in 8-lead SOIC versions. The SOIC 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-constrained 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
5-lead SC70 and TSOT packages, and 8-lead SOIC packages
with A, B, and C grade selections. All parts are specified over
the extended industrial (–40°C to +125°C) temperature range.

ADRO1, ADR02, and ADR03 are component-level compatible with REF01, REF02, and REF03, respectively. No guarantees for system-level compatibility are implied.
SOIC versions of ADR01/ADR02/ADR03 are pin-to-pin compatible with 8-lead SOIC versions of REF01/REF02/REF03, respectively, with the additional temperature
monitoring function.
