DEVICE DESCRIPTION
The ZRA124 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 1.24 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 ZRA124 design provides a stable voltage
without an external capacitor and is stable with
capacitive loads. The ZRA124 is recommended
for operation between 50
μ
A 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.
