httpsThe ZR423 uses a bandgap circuit design toachieve a precision micropower voltagereference of 1.25 volts. The device isavailable in a TO92 style package for throughhole requirements.

The ZR423 design provides a stable voltagewithout an external capacitor and is stablewith capacitive loads. The ZR423 isrecommended for operation between 50µAand 5mA and so is ideally suited to lowpower and battery powered applications.

Battery powered and portable

equipment.

Metering and measurement systems. Instrumentation.

Data acquisition systems.Precision power supplies.

t.comExcellent performance is maintained to anabsolute maximum of 25mA, however therugged design and 20 volt processing allowsthe reference to withstand transient effectsand currents up to 200mA. Superiorswitching capability allows the device toreach stable operating conditions in only afew microseconds.
