DEVICE DESCRIPTION
The ZR4040-2.5 uses a bandgap circuit
design to achieve a precision micropower
voltage reference of 2.5 volts. The device is
available in small outline surface mount
packages, ideal for applications where space
saving is important, as well as packages for
through hole requirements.
The ZR4040-2.5 design provides a stable
voltage without an external capacitor and is
stable with capacitive loads. The ZR4040-2.5
is recommended for operation between
60
µA and 15mA and so is ideally suited to
l o w
po w e r
an d
ba tt e ry
p o we re d
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 SOT23 packages
TO92 style package
No stabilising capacitor required
Typical TC 30ppm/°C
Typical slope resistance 0.4Ω
2% 1% and 0.5 % tolerance
Industrial temperature range
Operating current 60µA to 15mA
Transient response, stable in less than
10
µs
APPLICATIONS
Battery powered and portable
equipment.
Metering and measurement systems.
Instrumentation.
Test equipment.
Data acquisition systems.
Precision power supplies.
