LM368-2.5 Datasheet | National Semiconductor

Description The LM368-2 5 is a precision monolithic temperature-pensated 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 Features Y Y Y Y Y Y Y Y 400 m A operating current Low output impedance Excellent line regulation ( 0001% V typical) Single-supply operation Externally trimmable Low temperature coefficient Excellent initial accuracy (0 02% typical) Best reference available for low-voltage operation (VS e 5V VREF e 2 500V) Connection Diagram Metal Can Package (TO-5) TL H 8446 - 1 Top View case connected to Vb Order Number LM368H-2 5 LM368YH-2 5 See NS Package Number H08C Typical Applications Low Voltage Reference TL H 8446 - 2 C1995 National Semiconductor Corporation TL H 8446 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 Storage Temperature Range Operating Temperature Range 35V 600 m W b 60 C to a 150 C 0 C to a 70 C Soldering Information TO-5 (H) Package (10 sec ) a 300 C See AN-450 ‘‘Surface Mounting Methods and Their Effect on Product Reliability’’ (Appendix D) for other methods of soldering surface mount devices Electrical Characteristics (Note 1) LM368-2 5 Parameter Conditions Typical g 0 02 Tested...
