Overview
The ADM7150ACPZ-1.8-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 range and delivers up to 800 mA of output current at a fixed 1.8 V voltage. The device features a typical quiescent current of 4.3 mA and a shutdown current of 0.1 µA. It provides excellent power supply rejection exceeding 90 dB from 1 kHz to 100 kHz and achieves low output noise with a spectral density of 1.7 nV/√Hz from 10 kHz to 1 MHz. The component is housed in an 8-lead LFCSP package.
Feature Summary
- Ultralow output noise performance suitable for sensitive RF applications
- High power supply rejection ratio across wide frequency ranges
- Capable of delivering up to 800 mA output current
- 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 reel quantity and tape specifications before procurement. Confirm that the 1.8 V fixed output variant aligns with the target circuit design requirements. Ensure compatibility with the 8-lead LFCSP footprint during PCB layout planning. Check for any regional distribution restrictions or moisture sensitivity level handling requirements prior to assembly.
Selection Notes
Select this component when designing circuits requiring minimal output noise and high line regulation for RF signal integrity. Consider the 4.5 V minimum input voltage constraint relative to the 1.8 V output to ensure adequate headroom. Evaluate thermal dissipation capabilities based on the expected load current and ambient temperature conditions. Verify that the available 800 mA current rating meets the peak demand of the connected load.
Part Context
This part belongs to the ADM7150 series 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 within the same package family. It utilizes an advanced proprietary architecture to achieve superior transient response and stability with ceramic capacitors. The device integrates internal protection features including thermal overload and current limiting.
Replacement Considerations
Consult the official datasheet for direct pin-compatible alternatives within the ADM7150 family offering different fixed output voltages. Verify electrical parameter equivalence for any cross-referenced components from other manufacturers.
