ZRT050
4.9V LOW POWER PRECISION REFERENCE SOURCE
Description
The ZRT050 is a monolithic integrated circuit providing a
precise stable reference voltage of 4.9V at 500μA.
The circuit features a knee current of 150μA and operation
over a wide range of temperatures and currents.
The ZRT050 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 the
schematic diagram. 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.
