GENERAL DESCRIPTION
Available in the industrial temperature range of −40°C to
+125°C, the ADR130 is housed in a tiny TSOT package.
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.
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).

Long-Term Stability
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

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.
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.

ADR130
THEORY OF OPERATION
The ADR130 sub-band gap reference is the high performance
solution for low supply voltage and low power applications. The
uniqueness of this product lies in its architecture.
INPUT CAPACITOR
Input capacitors are not required on the ADR130. There is no
limit for the value of the capacitor used on the input, but a 1 ꢀF
to 10 ꢀF capacitor on the input improves transient response in
applications where there is a sudden supply change. An addi-
tional 0.1 ꢀF capacitor in parallel also helps reduce noise from
the supply.
POWER DISSIPATION CONSIDERATIONS
The ADR130 is capable of delivering load currents to 4 mA
with an input range from 3.0 V to 18 V. When this device is
used in applications with large input voltages, care must be
taken to avoid exceeding the specified maximum power
dissipation or junction temperature, because this results in
premature device failure.
OUTPUT CAPACITOR
The ADR130 requires a small 0.1 ꢀF output capacitor for
stability. Additional 0.1 ꢀF to 10 ꢀF capacitance in parallel can
improve load transient response. This acts as a source of stored
energy for a sudden increase in load current. The only parame-
ter affected by the additional capacitance is turn-on time.
Use the following formula to calculate the maximum junction
temperature or dissipation:
TJ − TA
PD =
θJA
where:
TJ is the junction temperature.
TA is the ambient temperature.
PD is the device power dissipation.
θJA is the device package thermal resistance.

Two reference ICs are used and fed from an unregulated input,
VIN. The outputs of the individual ICs that are connected in
series provide two output voltages, VOUT1 and VOUT2. VOUT1 is the
terminal voltage of U1, and VOUT2 is the sum of this voltage and
the terminal voltage of U2. U1 and U2 are chosen for the two
voltages that supply the required outputs (see Table 5). For
example, if U1 is set to have an output of 1 V or 0.5 V, the user
can stack on top of U2 to get an output of 2 V or 1.5 V.

STACKING REFERENCE ICs FOR
ARBITRARY OUTPUTS
Some applications may require two reference voltage sources
that are a combined sum of the standard outputs. Figure 34 and

implemented.

PRECISION CURRENT SOURCE
NEGATIVE PRECISION REFERENCE WITHOUT
PRECISION RESISTORS
In low power applications, the need can arise for a precision
current source that can operate on low supply voltages. The
ADR130 can be configured as a precision current source (see
Figure 37). The circuit configuration shown is a floating current
source with a grounded load. The reference output voltage is
bootstrapped across RSET, which sets the output current into the
load. With this configuration, circuit precision is maintained for
load currents ranging from the reference supply current,
typically 85 μA, to approximately 4 mA.
A negative reference is easily generated by adding an op amp,
A1, and is configured as shown in Figure 36. VOUT is at virtual
ground and, therefore, the negative reference can be taken
directly from the output of the op amp. The op amp must be
dual-supply, low offset, and rail-to-rail if the negative supply
voltage is close to the reference output.
