Ultralow Noise, High Rejection Low Dropout Regulators Analog Devices Introduces the World’s Lowest Noise LDO The ADM7154/ADM7155 are ultralow noise LDO (low dropout) regulators for RF (radio frequency) signal devices. The ADM7154/ADM7155 operate from 2.3 V to 5.5 V, provide up to 600 mA of output current, and support output voltages from 1.2 V to 3.3 V. The LDOs achieve an output NSD (noise spectral density) of 1.5 nV/√Hz above 100 kHz, which significantly reduces VCO (voltage controlled oscillator) phase noise in point-to-point microwave radios, satellite communications, defense electronics, and other wideband applications.

Maximum 240 mA and 500 mA of current, respectively, distributed between four independent outputs, enable the HMC860LP3E and HMC1060LP3E to supply all of the power needs of wideband PLL with integrated VCO products, such as the HMC830LP6GE. An integrated PTAT (proportional to absolute temperature) feature, enabled via an external pin, allows the HMC1060LP3E to scale the supply voltage with temperature in order to maximize phase noise and output power performance of wideband with integrated VCO products, as well as other devices powered by the HMC1060LP3E.
