LM1403/LM1403A

Precision 2.50V Reference

General Description

Features

Low cost

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-

Low 400 mA operating current

Low output impedance (0.15X)

Excellent line regulation (0.0001%/V typical)

cient (Tempco) of V

OUT

(as low as 11 ppm/ C), along with

Single-supply operation

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.

Low temperature coefficient

Excellent initial accuracy (0.05% typical)

Excellent for low-voltage operation

For tighter specs, refer to LM368-2.5
