Precision 2.5 V, 5.0 V, and 10.0 V

Voltage References

REF01/REF02/REF03

GENERAL DESCRIPTION

FEATURES

High output accuracy

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.

REF01: 10.0 V, 0.3ꢀ maximum

REF02: 5.0 V, 0.3ꢀ maximum

REF03: 2.5 V, 0.6ꢀ maximum

Adjustable output: 3ꢀ minimum

Excellent temperature stability

REF01: 8.5 ppm/°C maximum

REF02: 8.5 ppm/°C maximum

REF03: 50 ppm/°C maximum

Low noise

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.

REF01: 30 μV p-p typical

REF02: 15 μV p-p typical

The small footprint, wide supply range, and application

versatility make the REF0x series of references ideal for general-

purpose and space-constrained applications.

REF03: 6 μV p-p typical

High supply voltage range: up to 36 V maximum

Low supply current: 1.4 mA maximum

High load-driving capability: 10 mA maximum

Temperature output function

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 pin-

for-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

Long-Term Stability (ΔV_{OUT_LTD}

)

Dropout Voltage (V_DO

)

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.

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.

where:

V_OUT(t₀) is V_OUTat 25°C at time 0.

_OUT(t₁) is V_OUTat 25°C after 1000 hours of operation at 25°C.

Temperature Coefficient (TCV_O)

V

The temperature coefficient relates the change in output voltage

to the change in ambient temperature of the device, as normal-

ized by the output voltage at 25°C. This parameter is expressed

in ppm/°C and can be determined by the following equation:

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.

in either microvolts per milliamp, ppm per milliamp, or ohms

of DC output resistance. This parameter accounts for the effects

of self-heating.

V_OUT(T₂) is output voltage at temperature 2.

Thermally Induced Output Voltage Hysteresis (ΔV_{OUT_HYS}

Thermally induced output voltage hysteresis represents the

change in output voltage after the device is exposed to a

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 V_BEvalues of these transistors produces a

proportional-to-absolute temperature current (PTAT) through

R14, and, when combined with the V_BEof Q19, produces a band

gap voltage, V_BG, 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 perfor-

mance 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, V_Ois 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.

OUTPUT ADJUSTMENT

The REF0x trim terminal can be used to adjust the output

up or down from the internally trimmed, nominal 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

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.

TEMPERATURE MONITORING

In addition to the optional TRIM function, the REF0x series of

references provides the ability to monitor changes in temper-

ature 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 (V_TEMP) is approximately

550 mV at 25°C, with a temperature coefficient (TCV_TEMP) of

approximately 1.96 mV/°C. Refer to Figure 32 for a graph of

output voltage vs. temperature.

BURN-IN

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.

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.

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 V_OUT. 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 neces-

sary 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

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:

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.

Because of this relationship, acceptable load current in high-

temperature 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.

Unlike most references, the quiescent current of the REF0x

constructed by configuring the reference as shown in Figure 39.

In this configuration, the negative rail is generated simply

with an inverting amplifier with a gain of −1. A low offset

op amp should be used to minimize the voltage error at the

negative output.

The voltage output from the op amp can be adjusted by

changing the value of the potentiometer: as shown, the op

amp outputs +2.5 V when the pot is pulled completely high,

and −2.5V when pulled completely low. In this configuration,

the load current is sourced by the op amp; therefore, a low

offset op amp with a current rating that meets or exceeds the

current requirements of the load should be used.
