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 Tj = 25°C, VIN = 6V, IL = 1mA and CL = 2.2µF.
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 SPX1521 is tested at 25°C for IL = 1 mA. For TJ = 125°C, line regulation is
guaranteed 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.
