NCV4264-2C Linear Regulator, Low Dropout, Low I Q The NCV42642C is a low quiescent current consumption LDO regulator. Its output stage supplies 100 mA with 2.0% output www.onsemi.com voltage accuracy. Maximum dropout voltage is 500 mV at 100 mA load current. MARKING It is internally protected against 45 V input transients, input supply DIAGRAM reversal, output overcurrent faults, and excess die temperature. No external components are required to enable these features.
