ZRT100GC2TA

ZRT100 9.8V LOW POWER PRECISION REFERENCE SOURCE DESCRIPTION The ZRT100 is a monolithic integrated circuit providing 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 s h o w n i n Fi g. 1 . Thi s f a c i l i t y i s use d w h e 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. SOT223 FEATURES • Trimmable output • Excellent temperature stability • Low output noise figure • Available in two temperature ranges • 1 and 2% initial voltage tolerance versions available • No external stabilising capacitor required in most cases • Low slope resistance SOT223 Package suffix G • SOT223 small outline package Top view (pin 4 floating or connected to pin 2) ORDERING INFORMATION DEVICE TOL% OPERATING TEMP.
