Very Low Iq Low Dropout Linear Regulator

The NCV8664 is a precision 3.3 V and 5.0 V fixed output, low dropout integrated voltage regulator with an output current capability of 150 mA. Careful management of light load current consumption, combined with a low leakage process, achieve a typical quiescent current of 22 μA.
NCV8664 is pin and functionally compatible with NCV4264 and NCV4264−2, and it could replace these parts when very low quiescent current is required.
The output voltage is accurate within ±2.0%, and maximum dropout voltage is 600 mV at full rated load current.
It is internally protected against input supply reversal, output overcurrent faults, and excess die temperature. No external components are required to enable these features.
