The LM368-2 5 is a precision monolithic temperature-compensated voltage reference The LM368-2 5 makes use of thin-film technology enhanced by the discrete laser trimming of resistors to achieve excellent Temperature coefficient (Tempco) of VOUT (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 electromigration in the trimmed area The LM368-2 5 also provides 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
