LM368-5.0 and LM368-10 Precision Voltage References

General Description

Features

300 mA operating current

The LM368 is a precision, monolithic, temperature-compen-

sated voltage reference. The LM368 makes use of thin-film

technology enhanced by the discrete laser trimming of re-

sistors to achieve excellent Temperature coefficient

Low output impedance

Excellent line regulation (.0001%/V typical)

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 also provides

excellent stability vs. changes in input voltage and output

current (both sourcing and sinking). This device is available

in output voltage options of 5.0V and 10.0V and will operate

in both series or shunt mode. Also see the LM368-2.5 data

sheet for a 2.5V output. The devices are short circuit proof

when sourcing current. A trim pin is made available for fine
