Analog Devices, Inc. (NASDAQ: ADI), a global leader in high-performance semiconductors for signal processing applications, announced today the release of ultra-low-noise LDO (low-dropout) regulators for RF (radio frequency) signal devices. The ADM7150/1 operate from 4.5 V to 16 V, provide up to 800-mA of output current and support output voltages from 1.5 to 5.0 V. The LDOs achieve an output-NSD (noise spectral density) of 1.4 nV/rtHz from 10 kHz to 1 MHz, which significantly reduces VCO (voltage-controlled oscillator) phase noise in point-to-point microwave radios, satellite communications, defense electronics and other wideband applications. Additionally, a user adjustable C BYP can significantly reduce low frequency 1/f noise (8 nV/rtHz at 100 Hz) for precision analog front-end measurement systems.
