ZRA125
PRECISION 1.25 VOLT MICROPOWER VOLTAGE REFERENCE
DESCRIPTION
FEATURES
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.
The ZRA125 design provides a stable voltage without
an external capacitor and is stable with capacitive
loads. The ZRA125 is recommended for operation
between 50A and 5mA 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.
Superior switching capability allows the device to
reach stable operating conditions in only a few
microseconds.
No stabilizing capacitor required
Typical TC 30ppm/°C
Typical slope resistance 0.65
± 3% and 2% tolerance
Industrial temperature range
Operating current 50A to 5mA
Transient response, stable in less than 10s
Small outline SOT23 package
APPLICATIONS
Battery powered and portable equipment
Metering and measurement systems
Instrumentation
Data acquisition systems
