MICROPOWER VOLTAGE REFERENCE
ISSUE 2 - MARCH 1998
ZREF12
DEVICE DESCRIPTION
The ZREF12 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 1.24 volts. The device is
available in a small outline surface mount
package, ideal for applications where space
saving is important, as well as packages for
through hole requirements.
The ZREF12 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZREF12 is
recommended for operation between 50µA
and 5mA and so is ideally suited to low
power and battery powered applications.
Excellent performance is maintained to an
absolute maximum of 25mA, however the
rugged design and 20 volt processing allows
the reference to withstand transient effects
and currents up to 200mA. Superior
switching capability allows the device to
reach stable operating conditions in only a
few microseconds.
FEATURES
• Small outline SO8 and TO92 style
packages
• No stabilising capacitor required
• Typical TC 30ppm/°C
• Typical slope resistance 0.65Ω
• ± 1% tolerance
• Industrial temperature range (Military
temperature range available on request)
• Operating current 50µA to 5mA
• Transient response, stable in less than
10µs
• Alternative package options and
tolerances available
APPLICATIONS
• Battery powered and portable
equipment.
• Metering and measurement systems.
• Instrumentation.
• Precision power supplies.
• Test equipment.
• Data acquisition systems
