LM1403A Datasheet | National Semiconductor

Description The LM1403 is a precision monolithic temperature-pensated voltage reference The LM1403 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 LM1403 also provides excellent stability vs changes in input voltage and output current The output is current-limited and is short circuit proof Features Y Y Y Y Y Y Y Y Low cost Low 400 m A operating current Low output impedance (0 15X) Excellent line regulation (0 0001% V typical) Single-supply operation Low temperature coefficient Excellent initial accuracy (0 05% typical) Excellent for low-voltage operation (VS e 5V VREF e 2 500V) For tighter specs refer to LM368-2 5 Connection Diagram Dual-In-Line Package TL H 9757 - 1 Top View Order Number LM1403N or LM1403AN See NS Package Number N08E Typical Applications Low Voltage Reference TL H 9757 - 2 C1995 National Semiconductor Corporation TL H 9757 RRD-B30M115 Printed in U S A Absolute Maximum Ratings (Note 7) If Military Aerospace specified devices are required please contact the National Semiconductor Sales Office Distributors for availability and specifications Input Voltage Power Dissipation Output Short-Circuit Duration 40V 600 m W Continuous Storage Temperature Range Operating Temperature Range Lead Temperature (Soldering 10 sec ) ESD rating to be determined b 60 C to a 150 C 0 C to a 70 C 260 C Electrical Characteristics (Note 1) LM1403 LM1403A Parameter Conditions Typical a 2 500 g 0 05 g 0 04 g1 0 g0 4 Tested Limit (Note 2) Design Limit (Note 3) Units (Max Unless Noted) V % % m V m V % 100 m W m A m A V VOUT VOUT Error LM1403 LM1403A Line Regulation Load Regulation (Note 8) Thermal Regulation Quiescent...
