SEMICONDUCTORS
DESCRIPTION
TheZRT100isamonolithicintegratedcircuitproviding
a precise stable reference voltage of 9.8V at 500µA.
The circuit features a knee current of 150µA and
operation over a wide range of temperatures and
currents.
The ZRT100 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
facilityisnotused,thepin shouldbeleftopencircuit.
