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.
The ADR01, ADR02, ADR03, and ADR06 A grade in 8-lead
SOIC are qualified for automotive applications.
GENERAL DESCRIPTION
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 replacements1 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.

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