Temperature output function
The REF0x series of precision voltage references provide a
stable 10.0 V, 5.0 V, or 2.5 V output with minimal change in
response to variations in supply voltage, ambient temperature
or load conditions. The parts are available in 8-lead SOIC,
PDIP, CERDIP, and TO-99 packages, as well as 20-terminal
LCC packages (883 only), furthering the parts’ usability in
both standard and high stress applications.
With an external buffer and a simple resistor network, the
TEMP terminal can be used for temperature sensing and
approximation. A TRIM terminal is also provided on the
device for fine adjustment of the output voltage.
The small footprint, wide supply range, and application
versatility make the REF0x series of references ideal for generalpurpose and space-constrained applications.
Newer designs should use the ADR0x series of references,
which offer higher accuracy and temperature stability over a
wider operating temperature range, while maintaining full pinfor-pin compatibility with the REF0x series. This data sheet
applies to commercial-grade products only. Contact sales or
visit analog.com for military-grade (883) data sheets.

TERMINOLOGY
Dropout Voltage (VDO)
Dropout voltage, sometimes referred to as supply voltage
headroom or supply-output voltage differential, is defined as
the minimum voltage differential between the input and output
necessary for the device to operate.
VDO = (VIN − VOUT )min
ΔVOUT _ LTD = VOUT (t 1 ) − VOUT (t 0 )[V ]
IL = constant
ΔVOUT _ LTD =
Since the dropout voltage depends upon the current passing
through the device, it is always specified for a given load
current.
Temperature Coefficient (TCVO)
The temperature coefficient relates the change in output voltage
to the change in ambient temperature of the device, as normalized by the output voltage at 25°C. This parameter is expressed
in ppm/°C and can be determined by the following equation:
TCVOUT =
Long-Term Stability (ΔVOUT_LTD)
Long-term stability refers to the shift in output voltage at 25°C
after 1000 hours of operation in a 25°C environment. This may
also be expressed as either a shift in voltage or a difference in
ppm from the nominal output.
VOUT (T2 ) − VOUT (T1 )
VOUT (25 o C )× (T2 − T1 )
[
× 10 6 ppm/ o C
]
where:
VOUT(25°C) is output voltage at 25°C.
VOUT(T1) is output voltage at temperature 1.
VOUT(T2) is output voltage at temperature 2.
Thermally Induced Output Voltage Hysteresis (ΔVOUT_HYS)
Thermally induced output voltage hysteresis represents the
change in output voltage after the device is exposed to a
specified temperature cycle. This may be expressed as either a
shift in voltage or a difference in ppm from the nominal output.
VOUT (25 o C ) − VOUT _ TC
VOUT (25 o C )
VOUT (t 0 )
× 10 6 [ppm]
where:
VOUT(t0) is VOUT at 25°C at time 0.
VOUT(t1) is VOUT at 25°C after 1000 hours of operation at 25°C.
Line Regulation
Line regulation refers to the change in output voltage in
response to a given change in input voltage. It is expressed in
either percent per volt, ppm per volt, or microvolt per volt
change in input voltage. This parameter accounts for the effects
of self-heating.
Load Regulation
Load regulation refers to the change in output voltage in
response to a given change in load current, and is expressed
in either microvolts per milliamp, ppm per milliamp, or ohms
of DC output resistance. This parameter accounts for the effects
of self-heating.
VOUT _ HYS = VOUT (25 o C ) − VOUT _ TC [V ]
VOUT _ HYS =
VOUT (t 1 ) − VOUT (t 0 )
× 10 6 [ppm ]
where:
VOUT(25°C)is output voltage at 25°C.
VOUT_TC is output voltage after temperature cycling.
Thermal hysteresis occurs mainly as a result of forces exhibited
upon the internal die by its packaging. The effect is more
pronounced in parts with smaller packages.

REF01/REF02/REF03
THEORY OF OPERATION
REF01, REF02, and REF03 are high precision, low drift 10.0 V,
5.0 V, and 2.5 V voltage references available in a variety of
packages. These devices are standard band gap references (see
Figure 33). The band gap cell contains two NPN transistors
(Q18 and Q19) that differ in emitter area by a factor of 2. The
difference in the VBE values of these transistors produces a
proportional-to-absolute temperature current (PTAT) through
R14, and, when combined with the VBE of Q19, produces a band
gap voltage, VBG, that is almost constant over temperature.
While the REF0x series of references are designed to function
stably without any external components, connecting a 0.1 μF
ceramic capacitor to the output is highly recommended to
improve stability and filter out low level voltage noise. An
additional 1 μF to 10 μF electrolytic, tantalum, or ceramic
capacitor can be added in parallel to improve transient performance 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.
With an internal op amp and the feedback network created by
R5 and R6, VO is set precisely at 10.0 V, 5.0 V, or 2.5 V. Precision
laser trimming of various resistors and other proprietary circuit
techniques are used to further enhance the initial accuracy,
temperature curvature, and drift performance 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 additional 0.1 μF ceramic capacitor should be connected in
parallel to reduce supply noise.
The PTAT voltage is brought out directly from the band gap,
unbuffered, at the TEMP pin. Since this voltage output has a
stable 1.96 mV/°C temperature coefficient, users can estimate
the temperature change of the device by simply monitoring the
change in voltage at this pin.
Both input and output capacitors should be mounted as close to
the device pins as possible.

The REF0x trim terminal can be used to adjust the output

voltage. This feature allows the system designer to trim out
system errors due to changes in line and load conditions,
thermal hysteresis, output offset due to solder reflow, or other
error sources. The basic trim circuit configuration is shown
in Figure 35.

REF01/REF02/REF03
In addition to the optional TRIM function, the REF0x series of
references provides the ability to monitor changes in temperature by way of tracking the voltage present at the TEMP pin.
The output voltage of this pin is taken directly from the band
gap core and, as a result, varies linearly with temperature. The
nominal voltage at the TEMP pin (VTEMP) is approximately
550 mV at 25°C, with a temperature coefficient (TCVTEMP) of
approximately 1.96 mV/°C. Refer to Figure 32 for a graph of
output voltage vs. temperature.
As an example, given these ideal values, a voltage change of
39.2 mV at the TEMP pin corresponds to a 20°C change in
temperature.
The TEMP function is provided as a convenience, rather than a
precise feature, of the reference. In addition, because the voltage
at the TEMP pin is taken directly from the band gap core, any
current injected into or pulled from this pin has a significant
effect on VOUT. As such, even tens of microamps drawn from the
TEMP pin can cause the output to fall out of regulation. Should
the designer wish to take advantage of this feature, it is necessary to buffer the output of the TEMP pin with a low bias
current op amp, such as the AD8601 or AD8641. Any of these
op amps, if used as shown in Figure 36, causes less than a
100 μV change in VOUT.
It is important to understand that long-term stability is not
guaranteed by design, and that the output from the device may
shift beyond the typical 50 ppm specification at any time, especially
during the first 200 hours of operation. For systems that require
highly stable output over long periods of time, the designer should
consider burning-in the devices prior to use to minimize the
amount of output drift exhibited by the reference over time. Refer
to the AN-713 Application Note for more information regarding
the effects of long-term drift and how it can be minimized.
BURN-IN
Burn-in, wherein the part is powered and allowed to operate
normally for an extended period of time, can be useful for
minimizing the effects of long-term drift. A sample burn-in
circuit is shown below in Figure 37.

TEMPERATURE MONITORING

LONG-TERM STABILITY
One of the key parameters of the REF0x series of references is
long-term stability. Regardless of output voltage, internal testing
during development showed a typical drift of approximately
50 ppm after 1,000 hours of continuous, nonloaded operation
in a +25°C environment.
The REF0x series of voltage references are capable of sourcing
up to 10 mA of load current at room temperature across the
rated input voltage range. However, when used in applications
subject to high ambient temperatures, the input voltage and
load current should be carefully monitored to ensure that the
device does not exceeded its maximum power dissipation
rating. The maximum power dissipation of the device can be
calculated via the following equation:
PD =
T j − TA
θ JA
[W]
where:
PD is device power dissipation.
Tj is device junction temperature.
TA is ambient temperature.
θJA is package (junction-to-air) thermal resistance.
Because of this relationship, acceptable load current in hightemperature conditions may be less than the maximum
current-sourcing capability of the device. In no case should
the part be operated outside of its maximum power rating as
doing so may result in premature failure or permanent damage
to the device.

LOW COST CURRENT SOURCE
Unlike most references, the quiescent current of the REF0x

constructed by configuring the reference as shown in Figure 39.

By adding a mechanical or digital potentiometer, this circuit

However, since IQ typically varies from 0.55 mA to 0.65 mA,
this circuit should be limited to low precision, general-purpose
applications.
The output current sourcing capability of the REF0x series can
be boosted by using an external op amp and MOSFET, as shown

and −2.5V when pulled completely low. In this configuration,
the load current is sourced by the op amp; therefore, a low
