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.
