DEVICE 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 in a 3-pin metal can
package for through hole applications as
well as SOT223 and SO8 packages for
surface mount applications. Each package
option offers a trim facility whereby the
output voltage can be adjusted as shown in
F i g . 1. Thi s f a ci l i t y i s u sed w he n
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.
