1 / 14 page © Semiconductor Components Industries, LLC, 2004 August, 2004 − Rev. 0 1 Publication Order Number: NCP623/D NCP623 Ultra Low Noise 150 mA Low Dropout Voltage Regulator with ON/OFF Control Housed in a Micro8 t 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. Additionally, thermal shutdown and short−circuit protection provide the final product with a high degree of ruggedness. Features • Very Low Quiescent Current 170 mA (ON, no load), 100 nA (OFF, no load) • Very Low Dropout Voltage, Typical Value is 137 mV at an Output Current of 100 mA • Very Low Noise with External Bypass Capacitor (10 nF), Typically 25 mVrms over 100 Hz to 100 kHz • Internal Thermal Shutdown • Extremely Tight Line Regulation Typically −90 dB • Ripple Rejection −70 dB @ 1.0 kHz • Line Transient Response: 1.0 mV for DV in = 3.0 V • Extremely Tight Load Regulation, Typically 20 mV at DI out = 150 mA • Multiple Output Voltages Available • Logic Level ON/OFF Control (TTL−CMOS Compatible) • ESR can vary from 0 to 3.0 W Applications • All Portable Systems, Battery Powered Systems, Cellular Telephones, Radio Control Systems, Toys and Low Voltage Systems PIN CONNECTIONS See detailed ordering and shipping information on page 12 of this data sheet.
