Overview
The ADM7150ARDZ-3.3-R7 is an ultralow noise, high PSRR RF linear regulator manufactured by Analog Devices Inc. It operates from a 4.5 V to 16 V input range and provides up to 800 mA of output current with a fixed 3.3 V output voltage. The device features a typical quiescent current of 4.3 mA at no load and achieves excellent line and load transient response when used with a 10 µF ceramic output capacitor.
Feature Summary
- Ultralow output noise performance with spectral density of 1.7 nV/√Hz
- High power supply rejection ratio exceeding 90 dB across wide frequency ranges
- Optimized for stability using standard 10 µF ceramic capacitors
- Integrated thermal overload and short-circuit protection mechanisms
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs)
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R7 indicates reel packaging configuration. Confirm the ARDZ designation corresponds to the industrial temperature grade and SOIC package type. Ensure compatibility with required PCB layout guidelines for exposed pad grounding to maintain specified thermal resistance values.
Selection Notes
Select this component for applications requiring minimal output noise in radio frequency environments. Consider the 800 mA current capability against maximum load requirements. Evaluate the dropout voltage characteristics relative to the minimum available input voltage headroom under full load conditions.
Part Context
This part belongs to the ADM7150 series of low dropout linear regulators designed specifically for sensitive analog and RF circuits. The series offers various fixed output voltages and utilizes advanced proprietary architecture to deliver superior noise rejection compared to standard LDOs.
Replacement Considerations
Consult the official ordering guide for compatible variants such as adjustable versions or different output voltages within the same family. Verify pinout compatibility before substituting with other manufacturers' ultralow noise regulators.
