Description

The ZRC250A03 uses a bandgap circuit design to achieve a precision micropower voltage reference of 2.5 volts. The ZRC250A03 is available in a small outline surface mount package, ideal for applications where space saving is important, as well as a package for through hole requirements.

The ZRC250A03 design provides a stable voltage without an external capacitor and is stable with capacitive loads. The ZRC250A03 is recommended for operation between 20A 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 ZRC250A03 to reach stable operating conditions in only a few microseconds.
