LM368-2.5 Precision Voltage Reference

General Description

Features

400 mA operating current

The LM368-2.5 is a precision, monolithic, temperature-com-

pensated voltage reference. The LM368-2.5 makes use of

thin-film technology enhanced by the discrete laser trim-

ming of resistors to achieve excellent Temperature coeffi-

tight initial tolerance, (as low as 0.02%). The trim scheme is

such that individual resistors are cut open rather than being

trimmed (partially cut), to avoid resistor drift caused by elec-

tromigration in the trimmed area. The LM368-2.5 also pro-

vides excellent stability vs. changes in input voltage and

output current. The output is short circuit proof. A trim pin is
