DEVICE DESCRIPTION
The ZR12D uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 1.25 volts. The device is
available in a small outline SOT23 surface
mount package, ideal for applications where
space saving is important.
The ZR12D design provides a stable voltage
without an external capacitor and is stable
with cap acitive loa ds. The ZR12D is
recommended for operation between 50
µA
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 SOT23 package
No stabilising capacitor required
Typical TC 30ppm/°C
Typical slope resistance 0.65Ω
± 3% tolerance
Industrial temperature range
Operating current 50µA to 5mA
Transient response, stable in less than
10
µs
Alternative package options and
tolerances are available
APPLICATIONS
Battery powered and portable
equipment.
Metering and measurement systems.
Instrumentation.
Data acquisition systems.
Precision power supplies.
Test equipment.
