LM368-25 Precision Voltage Reference

General Description

The LM368-25 is a precision monolithic temperature-com-

pensated voltage reference The LM368-25 makes use of

thin-film technology enhanced by the discrete laser trim-

ming of resistors to achieve excellent Temperature coeffi-

cient (Tempco) of VOUT (as low as 11 ppm C) along with

tight initial tolerance (as low as 002%) 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 LM368-25 also pro-

vides excellent stability vs changes in input voltage and

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

made available for fine trimming of VOUT or for obtaining

intermediate values without greatly affecting the Tempco of

the device
