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 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 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

Note 2 Tested Limits are guaranteed and 100% tested in production
Note 3 Design Limits are guaranteed (but not 100% production tested) over the indicated temperature and supply voltage ranges These limits are used to
calculate outgoing quality levels
Note 4 Thermal Regulation is defined as the change in the output Voltage at a time T after a step change in power dissipation of 100 mW
Note 5 Temperature Coefficient of VOUT is defined as the worst case delta-VOUT measured at Specified Temperatures divided by the total span of the Specified
Temperature Range (See graphs) There is no guarantee that the Specified Temperatures are exactly at the minimum or maximum deviation
Note 6 Thermal Resistance is 160 C W junction to ambient soldered into a PC board
Note 7 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its Rated Operating Conditions (see Note 1 and Conditions)
Note 8 Load regulation is measured on the output pin at a point below the base of the package Regulation is measured at constant junction temperature
using pulse testing with a low duty cycle Changes in output voltage due to heating effects are covered under the specification for thermal regulation
