Overview
The ADM7150ARDZ-1.8 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 voltage range and provides a fixed 1.8 V output with up to 800 mA of current capability. The device features a typical quiescent current of 4.3 mA at no load and a low shutdown current of 0.1 µA. It delivers excellent line regulation of ±0.01 %/V and load regulation of 0.4 %/A. The component is housed in an 8-lead SOIC package.
Feature Summary
- Ultralow output noise performance suitable for sensitive RF applications
- High power supply rejection ratio across wide frequency ranges
- Stable operation with standard ceramic output capacitors
- Integrated thermal overload and short-circuit protection
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' against official documentation to confirm reel packaging requirements. Ensure the ordering code matches the exact 1.8 V fixed output variant. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement specifications.
Selection Notes
Select this component when designing circuits requiring minimal output noise and high ripple rejection for radio frequency stages. Verify that the input voltage remains within the specified 4.5 V to 16 V range under all operating conditions. Ensure adequate PCB layout practices are followed to maintain stability with the required ceramic capacitance values.
Part Context
This part belongs to the ADM7150 series of ultralow noise linear regulators designed specifically for demanding RF environments. The series offers various fixed output voltages while maintaining consistent electrical characteristics. The 8-lead SOIC package provides a compact footprint suitable for space-constrained designs requiring robust power management.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains the required 800 mA output current and ultralow noise specifications. Ensure thermal resistance and package dimensions match the existing design constraints.
