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. 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
REF02, and REF03. The small footprint and wide operating
range make the ADR0x references ideally suited for general­purpose and space-constrained applications.

to the industry-standard REF01,

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.

Table 1. Selection Guide

Part Number Output Voltage

ADR01 10.0 V
ADR02 5.0 V

With an external buffer and a simple resistor network, the
TEMP terminal can be used for temperature sensing and

ADR03 2.5 V
ADR06 3.0 V

approximation. A TRIM terminal is provided on the devices for
fine adjustment of the output voltage.

1

ADRO1, ADR02, and ADR03 are component-level compatible with REF01, REF02, and REF03, respectively. No guarantees for syste-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.
