NCP623
Ultra Low Noise
150 mA Low Dropout
Voltage Regulator with
ON/OFF Control
Housed in a Micro8 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 VRMS (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 s 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.
Additionally, thermal shutdown and shortcircuit protection
provide the final product with a high degree of ruggedness.
