PRECISION 2.5 VOLT MICROPOWER
VOLTAGE REFERENCE
ISSUE 4 - APRIL 2002
DEVICE DESCRIPTION
The ZRA250 uses a bandgap circuit design
to achieve a precision micropower voltage
reference of 2.5 volts. The device is available
in small outline surface mount packages,
ideal for applications where space saving is
important.
The ZRA250 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZRA250 is
recommended for operation between 50 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.
