(1)Specification applies over the full specified junction temperature range, 0
°
C to +125
°
C.
(2)REG1117 and REG1117A adjustable versions require a minimum load current for
±
3% regulation.
(3)Dropout voltage is the input voltage minus output voltage that produces a 1% decrease in output voltage.
(4)Percentage change in unloaded output voltage before versus after a 30ms power pulse of IO = 800mA (REG1117 models), IO = 1A (REG1117A),
VIN VO = 1.4V (reading taken 10ms after pulse).
