Data Sheet
APPLICATIONS INFORMATION
OVERVIEW
The ADR01/ADR02/ADR03/ADR06 are high precision, low
drift 10.0 V, 5.0 V, 2.5 V, and 3.0 V voltage references available
in an ultracompact footprint. The 8-lead SOIC versions of the
devices are drop-in replacements of the REF01/REF02/REF03
sockets with improved cost and performance.
ADR01/ADR02/ADR03/ADR06
ADR03 can be adjusted from 2.3 V to 2.8 V. Adjustment of the
output does not significantly affect the temperature performance
of the device, provided the temperature coefficients of the resis-
tors are relatively low.

The band gap cell contains two NPN transistors (Q18 and Q19)
that differ in emitter area by 2×. The difference in their V BE
produces a proportional-to-absolute temperature current (PTAT)

Although the ADR01/ADR02/ADR03/ADR06 are designed to
function stably without any external components, connecting a

capacitor can be added in parallel to improve transient per-
formance in response to sudden changes in load current;
however, the designer should keep in mind that doing so
increases the turn-on time of the device.
A 1 μF to 10 μF electrolytic, tantalum or ceramic capacitor can
also be connected to the input to improve transient response in
applications where the supply voltage may fluctuate. An addi-

tional 0.1 μF ceramic capacitor should be connected in parallel
to reduce supply noise. Mount both input and output capacitors
as close to the device pins as possible.
Output Adjustment
The ADR01/ADR02/ADR03/ADR06 trim terminal can be used
to adjust the output voltage over a nominal voltage. This feature
allows a system designer to trim system errors by setting the
reference to a voltage other than 10.0 V/5.0 V/2.5 V/3.0 V. For
finer adjustment, add a series resistor of 470 k?. With the con-
figuration shown in Figure 35, the ADR01 can be adjusted from
9.70 V to 10.05 V, the ADR02 can be adjusted from 4.95 V to
5.02 V, the ADR06 can be adjusted from 2.8 V to 3.3 V, and the

Temperature Monitoring

This output can be used to monitor the temperature change in the
system. The voltage at V TEMP is approximately 550 mV at 25°C,
and the temperature coefficient is approximately 1.96 mV/°C
(see Figure 36). A voltage change of 39.2 mV at the TEMP pin
corresponds to a 20°C change in temperature.
