The ADR01, ADR02, ADR03, and ADR06 are precision 10.0 V,
5.0 V, 2.5 V, and 3.0 V, respectively, band gap voltage references
featuring high accuracy, high stability, and low power
consumption. The devices are housed in tiny, 5-lead SC70 and
TSOT packages, as well as in 8-lead SOIC version. The SOIC
version of the ADR01, ADR02, and ADR03 are drop-in
replacements

to the industry-standard REF01, REF02, and REF03.
The small footprint and wide operating range make the ADR01,
ADR02, ADR03, and ADR06 references ideally suited for general-
purpose and space-constrained applications.
With an external buffer and a simple resistor network,
the TEMP pin can be used for temperature sensing and
approximation. A TRIM pin 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 a stable output voltage from
a wide supply voltage range. The devices are available in 5-lead
SC70 and TSOT packages and an 8-lead SOIC package with A,
B, and C grade selections. All devices are specified over the
extended industrial (−40°C to +125°C) temperature range. The
ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead SOIC
are qualified for automotive applications.

ADR01, 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, and ADR03 are pin-to-pin compatible with the 8-lead SOIC versions of the REF01, REF02, REF03, respectively, with the additional
temperature monitoring function.
