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 SPX2951 is tested at I
L
= 1mA. 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 100mV below
its nominal value measured at 1V differential. At very low values of programmed output voltage, the minimum input
supply voltage of 2V ( 2.3V over temperature) must be taken into account.

Note 7:
Comparator thresholds are expressed in terms of a voltage differential at the feedback terminal below the
nominal reference voltage measured at 6V input. To express these thresholds in terms of output voltage change,
multiply by the error amplifier gain = V
/V
= (R
+ R
)/R
For example, at a programmed output voltage of 5V,
the error output is guaranteed to go low when the output drops by 95mV x 5V/1.235 = 384mV. Thresholds remain
constant as a percent of V
OUT
as V

is varied, with the dropout warning occurring at typically 5% below nominal,
7.5% guaranteed.
