Note 1: Output or reference voltage temperature coefficients defined as the worst case voltage change divided by

the total temperature range.

Note 2: Unless otherwise specified all limits are guaranteed for T

Note 3: 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.

Note 4: Line regulation for the SPX1129 is tested at 25°C for I

by design.

Note 5: Dropout voltage is defined as the input to output differential at which the output voltage drops 100 mV below

its nominal value measured at 1V differential.
