DEVICE DESCRIPTION
The ZR423 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 1.25 volts. The device is
available in a TO92 style package for through
hole requirements.
The ZR423 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZR423 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 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.
