ZRC330Q

AUTOMOTIVE COMPLIANT LOW KNEE CURRENT 3.3V VOLTAGE REFERENCE

Description

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.

Automotive Compliant supporting PPAPs.
