Overview
The ADM7150ACPZ-4.5-R2 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 up to 800 mA of output current with a fixed 4.5 V output. 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 incorporates advanced proprietary architecture for superior power supply rejection and ultralow output noise.
Feature Summary
- Ultralow noise performance with 1.0 µV rms total integrated noise from 100 Hz to 100 kHz
- High power supply rejection ratio exceeding 90 dB from 1 kHz to 100 kHz at 400 mA load
- Low dropout voltage of 0.6 V at 800 mA load for efficient operation
- Integrated enable pin with low shutdown current of 0.1 µA
Applications
- RF mixers and phase-locked loops (PLLs)
- Voltage-controlled oscillators (VCOs) and PLLs with integrated VCOs
- Communications and infrastructure systems
- Cable digital-to-analog converter (DAC) drivers
- Backhaul and microwave links
Procurement Notes
Verify the specific ordering suffix matches the required package and tape/reel configuration. Confirm that the fixed 4.5 V output variant aligns with the design requirements. Ensure compatibility with the specified 8-lead LFCSP or SOIC packages. Check for any recent revision updates in the datasheet before finalizing procurement.
Selection Notes
Select this component for applications requiring high current capability combined with strict noise constraints. Ensure the input voltage remains within the 4.5 V to 16 V range under all operating conditions. Verify that the thermal management strategy accommodates the junction temperature limits during maximum load scenarios. Consider the minimum capacitance requirements for stability.
Part Context
This part belongs to the ADM7150 family of ultralow noise linear regulators designed specifically for radio frequency applications. The series offers various fixed output voltages ranging from 1.5 V to 5.0 V. It is engineered to provide high power supply rejection and minimal output noise, making it suitable for sensitive analog and RF circuits where signal integrity is critical.
Replacement Considerations
The ADM7151 is an adjustable LDO alternative mentioned in the documentation for generating additional output voltages. No other direct substitute part numbers are confirmed in the provided source material.
