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 guaranteed for TJ = 25°C, VIN = 6V, IL = 100µA and CL = 1µF.
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 SPX1121 is tested at IL = 1mA. For TJ = 125°C, line regulation is guaranteed
by design. See typical performance characteristics for line regulation versus temperature and load
current.
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.
