This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more
susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

APPLICATION INFORMATION
The REF50xx is family of low-noise, precision
bandgap voltage references that are specifically
designed for excellent initial voltage accuracy and
drift. Figure 22 shows a simplified block diagram of
the REF50xx.
SUPPLY VOLTAGE
The REF50xx family of voltage references features
extremely low dropout voltage. With the exception of
the REF5020, which has
a
minimum supply
requirement of 2.7 V, these references can be
operated with a supply of 200 mV above the output
voltage in an unloaded condition. For loaded
conditions, a typical dropout voltage versus load plot
is shown in Figure 6 of the Typical Characteristics.

Figure 23 shows the typical connections for the
REF50xx.
A
supply bypass capacitor ranging
between 1 mF to 10 mF is recommended. A 1-mF to
50-mF output capacitor (CL) must be connected from
VOUT to GND. The ESR value of CL must be less than
or equal to 1.5 Ω to ensure output stability. To
minimize noise, the recommended ESR of CL is
between 1 Ω and 1.5 Ω.
Figure 24. VOUT Adjustment Using the TRIM/NR
Pin
The REF50xx allows access to the bandgap through
the TRIM/NR pin. Placing a capacitor from the
TRIM/NR pin to GND (see Figure 25) in combination
with the internal R3 and R4 resistors creates a
low-pass filter. A capacitance of 1 mF creates a
low-pass filter with the corner frequency between 10
Hz and 20 Hz. Such a filter decreases the overall
noise measured on the VOUT pin by half. Higher
capacitance results in a lower filter cutoff frequency,
further reducing output noise. Note that use of this
capacitor increases startup time.

The TEMP pin has high output impedance (see
Figure 22). Loading this pin with a low-impedance
circuit induces a measurement error; however, it does
not have any effect on VOUT accuracy. To avoid
errors caused by low-impedance loading, buffer the
TEMP pin output with a suitable low-temperature drift
op amp, such as the OPA333, OPA335, or OPA376,
as shown in Figure 26.

The REF50xx is designed for minimal drift error,
which is defined as the change in output voltage over
temperature. The drift is calculated using the box
method, as described by the following equation:

VOUT Temp Range
(1)
The REF50xx features a maximum drift coefficient of
3 ppm/°C for the high-grade version, and 8 ppm/°C
for the standard-grade.
The REF50xx family is specified to deliver current
loads of ±10 mA over the specified input voltage
range. The temperature of the device increases
according to the equation:
TJ = TA + PD × qJA
(2)
TEMPERATURE MONITORING
Where:
TJ = Junction temperature (°C)
TA = Ambient temperature (°C)
PD = Power dissipated (W)
The temperature output terminal (TEMP, pin 3)
provides a temperature-dependent voltage output
with approximately 60-kΩ source impedance. As
seen in Figure 8, the output voltage follows the
nominal relationship:
qJA
= Junction-to-ambient thermal resistance
(°C/W)
VTEMP PIN = 509 mV + 2.64 × T(°C)
The REF50xx junction temperature must not exceed
the absolute maximum rating of +150°C.
This pin indicates general chip temperature, accurate
to approximately ±15°C. Although it is not generally
suitable for accurate temperature measurements, it
can be used to indicate temperature changes or for
temperature compensation of analog circuitry. A
temperature change of 30°C corresponds to an
approximate 79 mV change in voltage at the TEMP
pin.
NOISE PERFORMANCE
Typical 0.1-Hz to 10-Hz voltage noise for each
member of the REF50xx family is specified in the
Electrical Characteristics: Per Device table. The noise
voltage increases with output voltage and operating
temperature. Additional filtering can be used to
improve output noise levels, although care should be
taken to ensure the output impedance does not
degrade performance.

APPLICATION CIRCUITS
DATA ACQUISITION
NEGATIVE REFERENCE VOLTAGE
Data acquisition systems often require stable voltage
references to maintain accuracy. The REF50xx family
features low noise, very low drift, and high initial
accuracy for high-performance data converters.
Figure 28 shows the REF5040 in a basic data
acquisition system.
For applications requiring a negative and positive
reference voltage, the REF50xx and OPA735 can be
used to provide a dual-supply reference from a 5-V
supply. Figure 27 shows the REF5020 used to
provide a 2.5-V supply reference voltage. The low
drift performance of the REF50xx complements the
low offset voltage and zero drift of the OPA735 to
provide an accurate solution for split-supply
applications. Care must be taken to match the
temperature coefficients of R1 and R2.

Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight
in homogeneous material)
