... Low Dropout Voltage Regulator with ON/OFF Control Housed in a Micro8t or QFN6 package, the NCP623 delivers up to 150 mA where it exhibits a typical 180 mV dropout. With an incredible noise level of 25 mVRMS (over 100 Hz to 100 kHz, with bypass capacitor), the NCP623 represents the ideal choice for sensitive circuits, especially in portable applications where noise performance and space are premium ...

... NCP623 Wake−up Improvement − In portable applications, an immediate response to an enable signal is vital. If noise is not of concern, the NCP623 without a bypass capacitor settles in nearly 20 ms and typically delivers 65 mVRMS between 100 Hz and 100 kHz. In ultra low−noise systems, the designer needs bypass capacitor to decrease the noise down to 25 mVRMS between 100 Hz and 100 kHz ...
