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.
