Description
The ZRC500 uses a bandgap circuit design to achieve a
precision micropower voltage reference of 5.0 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 ZRC500 design provides a stable voltage without an
external capacitor and is stable with capacitive loads. The
ZRC500 is recommended for operation between 25µA 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.
