NCV8664 - Low Dropout Linear Regulator

1 Semiconductor Components Industries, LLC, 2010 September, 2010 Rev. 181 Publication Order Number: NCV8664 /DNCV8664 Very Low Iq Low DropoutLinear RegulatorThe NCV8664 is a precision V and V fixed output, lowdropout integrated voltage Regulator with an output currentcapability of 150 mA. Careful management of light load currentconsumption, combined with a low leakage process, achieve atypical quiescent current of 22 is pin and functionally compatible with NCV4264 andNCV4264 2, and it could replace these parts when very lowquiescent current is output voltage is accurate within , and maximumdropout voltage is 600 mV at full rated load is internally protected against input supply reversal, outputovercurrent faults, and excess die temperature.
