DESCRIPTION

The ZRT040 is a monolithic integrated circuit providing

a precise stable reference voltage of 4.01V at 500

µA.

The circuit features a knee current of 150

µA and

operation over a wide range of temperatures and

currents.

The ZRT040 is available in a SOT223 package for

surface mount applications. This device offers a trim

facility whereby the output voltage can be adjusted as

shown in Fig.1. This facility is used when

compensating for system errors or setting the

reference output to a particular value. When the trim

facility is not used, the pin should be left open circuit.
