Overview
The ADM7150ACPZ-1.8-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 voltage range and provides up to 800 mA of output current with a fixed 1.8 V output. The device features a typical quiescent current of 4.3 mA at no load and a low shutdown current of 0.1 µA. It achieves excellent power supply rejection exceeding 90 dB from 1 kHz to 100 kHz and delivers an ultralow output noise of 1.0 µV rms from 100 Hz to 100 kHz. The component is housed in an 8-lead LFCSP package.
Feature Summary
- Ultralow output noise performance optimized for sensitive RF applications
- High power supply rejection ratio (PSRR) across a wide frequency range
- Capable of delivering up to 800 mA output current with minimal dropout voltage
- Operates stably with standard ceramic output capacitors
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 ordering suffix matches the required package type and tape-and-reel quantity. Confirm that the fixed 1.8 V output variant aligns with system design requirements. Ensure compatibility with the recommended minimum capacitance values for stable operation under varying load conditions.
Selection Notes
Select this regulator when ultralow noise and high PSRR are critical for RF signal integrity. Ensure the input voltage remains within the specified 4.5 V to 16 V range. Verify thermal management capabilities for the 8-lead LFCSP package if operating near maximum load currents.
Part Context
This component belongs to the ADM7150 series of low dropout linear regulators designed for radio frequency applications. The series offers various fixed output voltages and is characterized by its proprietary architecture that isolates the internal reference from input ripple. It serves as a compact power solution for systems requiring clean power delivery.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the same family. Verify that any substitute maintains equivalent noise spectral density and PSRR specifications for RF use cases.
