ZRB500
Precision 5V micropower voltage reference
Description
The ZRB500 uses a bandgap circuit design to Excellent performance is maintained to an
achieve
a
precision micropower voltage absolute maximum of 25mA, however the
reference of 5.0 volts. The device is available in rugged design and 20 volt processing allows
small outline surface mount packages, ideal for the reference to withstand transient effects and
applications where space saving is important, currents up to 200mA. Superior switching
as well as packages for through hole capability allows the device to reach stable
requirements.
operating conditions in only
microseconds.

The ZRB500 design provides a stable voltage
without an external capacitor and is stable with
capacitive loads. The ZRB500 is recommended
for operation between 50A and 15mA and so
is ideally suited to low power and battery
powered applications.
