Dual 125mA CMOS LDO in an SO-8 package. This part
offers 120mV dropout voltage on each output at 100mA typ-
ical (5V part), and nearly zero dropout below 5mA. Each
output is independently short-circuit protected.
Its all-CMOS design means that only 2.2A of current is
required to run the part.
2% accurate outputs come in a number of configurations,
to allow for flexible yet compact portable system designs.
