The ZRT062 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 F i g . 1 . Th i s f a c i l i t y i s use d w he n 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.
