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.

4: Line regulation for the SPX1121 is tested at I
= 1mA. For T
= 125

C, line regulation is guaranteed
by design. See typical performance characteristics for line regulation versus temperature and load
current.
N
OTE
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.
