PRECISION 1.25 VOLT  
MICROPOWER VOLTAGE REFERENCE  
ZRA125  
ISSUE 2 - FEBRUARY 1997  
DEVICE DESCRIPTION  
Typical TC 30ppm/°C  
Typical slope resistance 0.65Ω  
The ZRA125 uses a bandgap circuit design to  
achieve a precision micropower voltage  
reference of 1.25 volts. The device is available  
in small outline surface mount packages, ideal  
for applications where space saving is  
important, aswellaspackagesforthroughhole  
requirements.  
± 3%,2% and 1% tolerance  
Industrial temperature range  
Operating current 50µA to 5mA  
Transient response, stable in less than 10µs  
Optional extended current range  
The ZRA125 design provides a stable voltage  
without an external capacitor and is stable with  
capacitive loads. The ZRA125 is recommended  
for operation between 50µA and 5mA and so  
is ideally suited to low power and battery  
powered applications.  
APPLICATIONS  
Battery powered and portable equipment.  
Metering and measurement systems.  
Instrumentation.  
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.  
Data acquisition systems.  
Precision power supplies.  
Test equipment.  
FEATURES  
Small outline SOT23, SO8 and TO92 style  
packages  
No stabilising capacitor required
