ZRC330
DEVICE DESCRIPTION
The ZRC330 uses a bandgap circuit design to
achieve a precision micropower voltage
reference of 3.3 volts. The device is available
in small outline surface mount packages, ideal
for applications where space saving is
important.
The ZRC330 design provides a stable voltage
without an external capacitor and is stable with
capacitive loads. The ZRC330 is recommended
for operation between 20µA and 5mA 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.
