REF02 IC – 5V Precision Voltage Reference IC
The REF02 are industry-standard precision voltage references. The 5V output REF02 can also be adjusted over a ?6% range. The 5V REF02 has a single-supply operation over an input voltage range of 7V to 33V. Both devices offer a low-current drain of 1mA. The REF02 also provides a TEMP pin whose output voltage varies linearly with temperature, making this device suitable for a wide variety of temperature-sensing and control applications. For new designs, refer to the MAX6035 or MAX6143 data sheets.
REF02AP
The REF02 is a precision 5V voltage reference. The drift is
laser trimmed to 10ppm/?C max over the extended industrial
and military temperature range. The REF02 provides a stable
5V output that can be externally adjusted over a ?6% range
with minimal effect on temperature stability. The REF02
operates from a single supply with an input range of 8V to 40V
with a very low current drain of 1mA, and excellent temperature
stability due to an improved design. Excellent line and load
regulation, low noise, low power, and low cost make the
REF02 the best choice whenever a 5V voltage reference is
required. Available package options are DIP-8 and SO-8. The
REF02 is an ideal choice for portable instrumentation,
temperature transducers, Analog-to-Digital (A/D) and Digitalto-Analog (D/A) converters, and digital voltmeters.
REF02C
The REF01/REF02 are industry-standard precision voltage references. The stable 10V output of the REF01
can be adjusted over a ?6% range with minimal effect
on temperature stability. The 5V output REF02 can also
be adjusted over a ?6% range. The 10V REF01 has a
single-supply operation over an input voltage range of
13V to 33V, while the 5V REF02 has a single-supply
operation over an input voltage range of 7V to 33V.
Both devices offer a low-current drain of 1mA. The
REF02 also provides a TEMP pin whose output voltage
varies linearly with temperature, making this device
suitable for a wide variety of temperature-sensing and
control applications. For new designs, refer to the
MAX6035 or MAX6143 data sheets.

REF03 IC – 2.5V Precision Voltage Reference IC
The REF03 precision voltage reference provides a stable 2.5 V output, with minimal change for variations in supply voltage, ambient temperature, or loading conditions. Single-supply operation over an input voltage range of 4.5 V to 33 V with a current drain of 1 mA and good temperature stability is achieved using an improved band gap design. Primarily targeted at price sensitive applications, the REF03 is available in plastic mini DIPs and surface-mount small outline plastic packages. For improved performance or ?40?C to 125?C operation, see the ADR03 data sheet.
REF03GS
The REF01/REF02/REF03 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 devices are available in 8-lead SOIC, PDIP,
CERDIP, and TO-99 packages, as well as 20-terminal LCC
packages (883 only), furthering the usability of the devices 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 REF01/REF02/REF03 series of references
ideal for general-purpose and space-constrained applications.
Newer designs should use the ADR01/ADR02/ADR03/ADR06
series of references, which offer higher accuracy and temperature
REF191GS
The REF19x series precision band gap voltage references use a
patented temperature drift curvature correction circuit and
laser trimming of highly stable, thin-film resistors to achieve a
very low temperature coefficient and high initial accuracy.
The REF19x series is made up of micropower, low dropout
voltage (LDV) devices, providing stable output voltage from
supplies as low as 100 mV above the output voltage and
consuming less than 45 ?A of supply current. In sleep mode,
which is enabled by applying a low TTL or CMOS level to the
SLEEP pin, the output is turned off and supply current is
further reduced to less than 15 ?A.
The REF19x series references are specified over the extended
industrial temperature range (?40?C to 85?C) with typical
performance specifications over ?40?C to 125?C for
applications, such as automotive.
All electrical grades are available in an 8-lead SOIC package; the
PDIP and TSSOP packages are available only in the lowest
electrical grade.
