Low Dropout Regulator, Ultra High Accuracy, Low Iq, 500 mA with Power Good NCP3337 www.onsemi.com The NCP3337 is a high performance, low dropout regulator. With accuracy of 0.9% over line and load and ultralow quiescent current and noise it encompasses all of the necessary features required by DFN10 todays consumer electronics. This unique device is guaranteed to be MN SUFFIX stable without a minimum load current requirement and stable with CASE 485C any type of capacitor as small as 1.0 F. The NCP3337 also comes equipped with sense and noise reduction pins to increase the overall utility of the device. The NCP3337 offers reverse bias protection. MARKING DIAGRAM Features Pin 1, 2.
