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

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 I
L
= 1 mA. For T
J
= 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.
Input Supply Voltage ....................................................... -20V to +20V
Shutdown Input Voltage ................................................. -0.6V to +6.5V
