NCP623  
Ultra Low Noise  
150 mA 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 a  
10 nF bypass capacitor), the NCP623 represents the ideal choice for  
sensitive circuits, especially in portable applications where noise  
performance and space are premium. The NCP623 also excels in  
response time and reacts in less than 25 ms when receiving an OFF to  
ON signal (with no bypass capacitor).  
Due to a novel concept, the NCP623 accepts output capacitors without  
any restrictions regarding their Equivalent Series Resistance (ESR) thus  
offering an obvious versatility for immediate implementation.  
With a typical DC ripple rejection better than −90 dB (−70 dB @  
1.0 kHz), it naturally shields the downstream electronics against  
choppy power lines.
