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 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.
The ZRC330Q has been qualified to AEC-Q100 Grade 1 and is Automotive Compliant supporting PPAPs.
