NCP623: Linear Voltage Regulator, LDO, Ultra Low Noise, with On/Off Control
Housed in a Micro8 or DFN6 package, the NCP623 Low Dropout Linear Voltage Regulator delivers up to 150 mA where it exhibits a typical 180 mV dropout. With an incredible noise level of 25 µVRMS (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 us 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 short-circuit protection provide the final product with a high degree of ruggedness.
