DC Power Conditioning

Analog Devices' DC power conditioning products are BiCMOS ultra-low-noise linear voltage regulators. Their high Power Supply Rejection Ratio (PSRR) in the 0.1 MHz to 10 MHz range provides excellent rejection of any preceding switching regulator or other power supply noise. The voltage output is ideal for frequency generation subsystems including Analog Devices' broad line of PLLs with integrated VCOs. The output voltage can be adjusted lower than the default value by using one external resistor.

The output for these linear voltage regulators can be set to 5 V by grounding the HV pin. The regulator can be powered-down by the TTL-compatible Enable input.

Expanding Analog Devices' DC power conditioning Line is the HMC1060LP3E. A maximum 500 mA of current, distributed between four independent outputs, enable the HMC1060LP3E to supply all of the power needs of Analog Devices' Wideband PLL with Integrated VCO products, such as the HMC830LP6GE.

Although targeted at Analog Devices' Wideband PLLs with Integrated VCO products, the HMC1060LP3E makes an excellent general-purpose regulator that supports adjustable output voltages ranging anywhere from 1.8 V to 5.2 V.
