A. VOUT(NOM) is the measured output voltage. VLIM is the
specified percentage of output voltage permitted to rise above the specified
VOUT(NOM). Iload is the load current applied on
VOUT. When VOUT falls to 98% of the nominal value
(VOUT(NOM)), the dropout current is recorded.

Measurement
A. Line regulation ΔVOUT / ΔVIN = 100µV/V (typ). For example
a 1V change in VIN (ΔVIN = 1V), results in a 100µV change
in VOUT (ΔVOUT = 100µV). Line regulation is a DC
parameter; therefore this waveform can only be considered valid after transients
die out or for a slow VIN slew rate.

A. Load regulation: ΔVOUT / ΔIOUT = 8mV/A (typ). For example
a 100mA change in IOUT (ΔIOUT = 100mA), results in a 0.8mV
(typ TPS7H1301) change in VOUT (ΔVOUT = 0.8mV). Load
regulation is a DC parameter; therefore this waveform can be considered valid
after transients die out or for a slow IOUT slew rate.
