The ZRT040 is a monolithic integrated circuit providing a precise stable reference voltage of 4.01V at 500mA.
The ZRT040 circuit features a knee current of 150mA and operation over a wide range of temperatures and currents.
The ZRT040 is available in a 3-pin metal can package for through hole applications as well as SOT223 and SO8 packages for surface mount applications. Each package option 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.
