LM1403/LM1403A
Precision 2.50V Reference
General Description
The LM1403 is a precision, monolithic, temperature-com-
pensated voltage reference. The LM1403 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 LM1403 also provides
excellent stability vs. changes in input voltage and output
current. The output is current-limited and is short circuit
proof.
