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. http://onsemi.com Micro8] DMR2 SUFFIX CASE 846A QFN10 MN SUFFIX CASE 485C Features • • • • • • • • • • • • High Accuracy Over Line and Load (+0.9% at 255C) Ultra−Low Dropout Voltage at Full Load (260 mV typ.)
