LM368-2 5 Precision Voltage Reference
General Description
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-
cient (Tempco) of V_OUT (as low as 11 ppm C) along with
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
made available for fine trimming of V_OUT or for obtaining
intermediate values without greatly affecting the Tempco of
the device
