Datasheet ILC7262CS-50-33, ILC7262CS-50-30, ILC7262CS-33-30 Datasheet (Impala Linear Corporation)

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.
