Description
The ZRC330 uses a bandgap circuit design to achieve a
precision micropower voltage reference of 3.3 volts. The
device is available in a small outline surface mount
package, 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 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.
