NCV4264-2 Linear Regulator, Low Dropout, Low I Q The NCV42642 is functionally and pin for pin compatible with NCV4264 with a lower quiescent current consumption. Its output www.onsemi.com stage supplies 100 mA with 2.0% output voltage accuracy. MARKING Maximum dropout voltage is 500 mV at 100 mA load current. DIAGRAM It is internally protected against 45 V input transients, input supply reversal, output overcurrent faults, and excess die temperature. No TAB external components are required to enable these features.
