PRECISION 5.0 VOLT MICROPOWER  
VOLTAGE REFERENCE  
ISSUE 3 - JANUARY 2003  
ZRB500  
DEVICE DESCRIPTION  
FEATURES  
Small outline SOT23 style package  
No stabilising capacitor required  
Typical TC 15ppm/°C  
The ZRB500 uses a bandgap circuit design to  
achieve a precision micropower voltage  
reference of 5.0 volts. The device is available  
in a small outline surface mount package,  
ideal for applications where space saving is  
important.  
Typical slope resistance 0.33  
± ±3%, 2% and 1% ±tolerance  
Industrial temperature range  
Operating current 50µA to 15mA  
Transient response, stable in less than  
10µs  
The ZRB500 design provides a stable voltage  
without an external capacitor and is stable  
with capacitive loads. The ZRB500 is  
recommended for operation between 50µA  
and 15mA and so is ideally suited to low  
power and battery powered applications.  
APPLICATIONS  
Battery powered and portable  
equipment.  
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.  
Metering and measurement systems.  
Instrumentation.  
Test equipment.  
Data acquisition systems.  
Precision power supplies.
