GENERAL DESCRIPTION
The REF02 precision voltage reference provides a stable 5 V
output that can be adjusted over a ±6% range with minimal
effect on temperature stability. Single-supply operation over an
input voltage range of 7 V to 40 V, low current drain of 1 mA,
and excellent temperature stability are achieved with an improved
band gap design. Low cost, low noise, and low power make the
REF02 an excellent choice whenever a stable voltage reference
is required. Applications include D/A and A/D converters,
portable instrumentation, and digital voltmeters. The versatility
of the REF02 is enhanced by its use as a monolithic temperature
transducer. For new designs, please refer to ADR02.

CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the REF02 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are
recommended to avoid performance degradation or loss of functionality.

OUTPUT ADJUSTMENT
+15V
The REF02 trim terminal can be used to adjust the output
voltage over a 5 V ±300 mV range. This feature allows the sys-
tem designer to trim system errors by setting the reference to a
voltage other than 5 V. Of course, the output can also be set to
exactly 5.000 V, or to 5.12 V for binary applications.

PRECISION CURRENT SOURCE
A current source with 35 V output compliance and excellent
output impedance can be obtained using this circuit. REF02
keeps the line voltage and power dissipation constant in device;
the only important error consideration at room temperature is
the negative supply rejection of the op amp. The typical 3 mV/V
PSRR of the OP02E will create an 20 ppm change (3 mV/V ꢃ
35 V/5 V) in output current over a 25 V range. For example, a
5 mA current source can be built (R = 1 kW) with 350 MW
output impedance.

Two REF01s and one REF02 can be stacked to yield 5.000 V,
15.000 V, and 25.000 V outputs. An additional advantage is
near-perfect line regulation of the 5.0 V and 15.0 V output. A
27 V to 55 V input change produces an output change that is
less than the noise voltage of the devices. A load bypass resistor
(RB) provides a path for the supply current (ISY) of the 15.000 V
regulator.

In general, any number of REF01s and REF02s can be stacked
this way. For example, 10 devices will yield 10 outputs in 5 V or
10 V steps. The line voltage can change from 100 V to 130 V.
However, care must be taken to ensure that the total load currents
do not exceed the maximum usable current (typically 21 mA).
