ON NCP3335MN330R2G Ultra high accuracy, low iq, 500 ma low dropout regulator Datasheet

NCP3335
Ultra High Accuracy,
Low Iq, 500 mA
Low Dropout Regulator
The NCP3335 is a high performance, low dropout regulator. With
accuracy of ±0.9% over line and load and ultra−low quiescent current
and noise it encompasses all of the necessary features required by
today’s consumer electronics. This unique device is guaranteed to be
stable without a minimum load current requirement and stable with
any type of capacitor as small as 1.0 mF. The NCP3335 also comes
equipped with sense and noise reduction pins to increase the overall
utility of the device.
