ZRB500
ISSUE 1 - OCTOBER 1995
DEVICE DESCRIPTION
FEATURES
•
Small outline SOT23,SO8 and TO92 style
packages
The ZRB500 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 5.0 volts. The device is available in
smalloutlinesurfacemount packages, idealfor
applications where space saving is important,
as well as packages for through hole
requirements.

No stabilising capacitor required
Typical TC 15ppm/ °C
Typical slope resistance 0.33Ω
± 3%, 2% and 1% tolerance
Industrial temperature range
Operating current 50µA to 15mA
Transient response, stable in less than 10µs
APPLICATIONS
The ZRB500 design provides a stable voltage
without anexternalcapacitorandisstablewith
capacitive loads.
The ZRB500 is
recommended for operation between 50µA
and 15mA and so is ideally suited to low power
and battery powered applications.
Excellent performance is maintained to a
suggested absolute maximum of 25mA,
however the rugged design and 20 volt
processing allows the reference to withstand
transient effects and currents up to 200mA.
Superiorswitchingcapabilityallowsthedevice
to reach stable operating conditions in only a
few microseconds.
Battery powered and portable equipment.
Metering and measurement systems.
Instrumentation.
Test equipment.
Data acquisition systems.
Precision power supplies.
