PRECISION 5.0 VOLT MICROPOWER
VOLTAGE REFERENCE
ISSUE 1 - OCTOBER 1995
DEVICE DESCRIPTION
The ZRB500 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 ZRB500 design provides a stable voltage
without an external capacitor and is stable with
capacitive loads.
recommended for operation between 50 A
and 15mA 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.
