DEVICE DESCRIPTION
The ZREF12 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 1.24 volts. The device is
available in a small outline surface mount
package, ideal for applications where space
saving is important, as well as packages for
through hole requirements.
The ZREF12 design provides a stable voltage
without an external capacitor and is stable
with capacitive loads. The ZREF12 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.
