NCV8664
Linear Regulator,
Low Dropout, Very Low Iq
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 mA.
NCV8664 is pin and functionally compatible with NCV4264 and
NCV42642, 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.
