ZRT025

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 500μA. The circuit features a knee current of 150μA 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.
