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.
