ZRC330Q
AUTOMOTIVE COMPLIANT LOW KNEE CURRENT 3.3V VOLTAGE REFERENCE
Description
Pin Assignments
The ZRC330Q 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 ZRC330Q design provides a stable voltage without an external
capacitor and is stable with capacitive loads. The ZRC330Q 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.
