ZRT025
2.5V LOW POWER PRECISION REFERENCE SOURCE
Description
The ZRT025 is a monolithic integrated circuit providing a
precise stable reference voltage of 2.5V at 500 μ A.
The circuit features a knee current of 150 μ A and operation

over a wide range of temperatures and currents.
The ZRT025 is available for surface mount applications. This
product 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.
