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. It includes thermal shutdown and current-limit protection.
Feature Summary
- Ultralow output noise performance for sensitive RF applications
- High power supply rejection ratio across wide frequency ranges
- Optimized stability with standard 10 µF ceramic output capacitors
- Integrated thermal overload and short-circuit protection
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs) and integrated PLLs
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links in communications infrastructure
Procurement Notes
Verify the specific suffix R7 indicates reel packaging upon procurement. Confirm the ARDZ designation matches the required industrial temperature grade (-40°C to +125°C). Ensure the 3.3 V fixed output variant aligns with system voltage requirements before ordering.
Selection Notes
Select this component for designs requiring high current capability alongside strict noise constraints. Verify that the input voltage remains within the specified 4.5 V to 16 V range under all operating conditions. Ensure adequate PCB thermal dissipation is available due to the exposed pad requirement for optimal heat transfer.
Part Context
This part belongs to the ADM7150 series of low dropout linear regulators designed specifically for radio frequency applications. It utilizes an advanced proprietary architecture to deliver superior noise and rejection characteristics compared to standard LDOs, making it suitable for demanding signal integrity environments.
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.
