Impala Linear Corporation ILC7262CS-50-33, ILC7262CS-50-30, ILC7262CS-33-30 Datasheet
Dual 125mA CMOS LDO in an SO-8 package. This part
offers 120mV dropout voltage on each output at 100mA typical (5V part), and nearly zero dropout below 5mA. Each
output is independently short-circuit protected.
Its all-CMOS design means that only 2.2µA 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.
