GENERAL DESCRIPTION
The ADR130 is the industry’s first family of tiny, micropower,
low voltage, high precision voltage references. Featuring 0.35%
initial accuracy and 25 ppm/°C of temperature drift in the tiny
TSOT-23 package, the ADR130 voltage reference only requires
80 μA for typical operation. The ADR130 design includes a
patented temperature drift curvature correction technique that
minimizes the nonlinearities in the output voltage vs. tempera-
ture characteristics.

Available in the industrial temperature range of −40°C to
+125°C, the ADR130 is housed in a tiny TSOT package.
For 0.5 V output, tie SET (Pin 5) to VOUT (Pin 4). For 1.0 V
output, tie SET (Pin 5) to GND (Pin 2).

TERMINOLOGY
Temperature Coefficient
Temperature coefficient is the change of output voltage with
respect to the operating temperature change normalized by the
output voltage at 25°C. This parameter is expressed in ppm/°C
and is determined by
( )TCVO
[ppm/°C]
=
VO (T2 ) VO (T1
VO (25°C) × T2
)
T1
× 106
where:
VO(25°C) = VO at 25°C.
VO(T1) = VO at Temperature 1.
VO(T2) = VO at Temperature 2.
Line Regulation
Line regulation is the change in the output due to a specified
change in input voltage. This parameter accounts for the effects
of self-heating. Line regulation is expressed in either %/V,
ppm/V, or μV/ΔVIN.
Load Regulation
Load regulation is the change in output voltage due to a
specified change in load current. This parameter accounts for
the effects of self-heating. Load regulation is expressed in either
mV/mA, ppm/mA, or dc output resistance (Ω).
ADR130
Long-Term Stability
Long-term stability is the typical shift of output voltage at 25°C
on a sample of parts subjected to a test of 1000 hours at 25°C.
ΔVO = VO (t0 ) VO (t1)

where:
VO(t0) = VO at 25°C at Time 0.
VO(t1) = VO at 25°C after 1000 hours operating at 25°C.
Thermal Hysteresis
Thermal hysteresis is the change of output voltage after the
device is cycled through temperatures from +25°C to −40°C to
+125°C, then back to +25°C. This is a typical value from a
sample of parts put through such a cycle.
where:
VO(25°C) = VO at 25°C.
VOTC = VO at 25°C after temperature cycle from +25°C to −40°C
to +125°C, then back to +25°C.
