REF02

+5V Precision

VOLTAGE REFERENCE

FEATURES

● OUTPUT VOLTAGE: +5V ±0.1% max

DESCRIPTION

The REF02 is a precision 5V voltage reference. The

drift is laser trimmed to 8.5ppm/°C max over the

extended industrial and military temperature range.

The REF02 provides a stable 5V output that can be

externally adjusted over a ±6% range with minimal

effect on temperature stability. REF02 operates from a

single supply with an input range of 8V to 40V with a

very low current drain of 1mA, and excellent tempera-

ture stability due to an improved design. Excellent line

and load regulation, low noise, low power, and low

cost make the REF02 the best choice whenever a 5V

voltage reference is required. All popular package

options are available: plastic DIP, and SOIC. The

REF02 is an ideal choice for portable instrumentation,

temperature transducers, A/D and D/A converters, and

digital voltmeter.

DISCHARGE SENSITIVITY

This integrated circuit can be damaged by ESD. Burr-Brown

recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling

and installation procedures can cause damage.

ESD damage can range from subtle performance degradation

to complete device failure. Precision integrated circuits may

be more susceptible to damage because very small parametric

changes could cause the device not to meet its published

specifications.

OUTPUT ADJUSTMENT

TYPICAL APPLICATIONS

The REF02 trim terminal can be used to adjust the voltage

over a 5V ±150mV range. This feature allows the system

designer to trim system errors by setting the reference to a

voltage other than 5V, including 5.12V⁽¹⁾for binary applica-

tions (see circuit on page one).

Adjustment of the output does not significantly affect the

coefficient change is approximately 0.7ppm/°C for 100mV of

output adjustment.

REFERENCE STACKING

PROVIDES OUTSTANDING LINE REGULATION

By stacking two REF01s and one REF02, a systems designer

can achieve 5V, 15V and 25V outputs. One very important

advantage of this circuit is the near perfect line regulation at

5V and 15V outputs. This circuit can accept a 27V to 55V

change to the input with less than the noise voltage as a

change to the output voltage. (R_B), a load bypass resistor,

supplies current (I_SY) for the 15V regulator.

Any number of REF01s and REF02s can be stacked in this

configuration. If ten devices can be stacked in this configu-

ration, for example, ten 5V or five 10V outputs are achieved.

The line voltage may range from 100V to 130V. Care should

be exercised to insure that the total load currents do not

exceed the maximum usable current which is typically

21mA.
