Overview
The ADM7154ARDZ-3.3-R7 is a fixed-output linear regulator providing 3.3 V at up to 600 mA load current. It operates from an input voltage range of 2.3 V to 5.5 V with a typical dropout voltage of 120 mV at full load. The device features ultralow noise, delivering 0.9 µV rms integrated noise (100 Hz to 100 kHz) and 1.5 nV/√Hz spectral density (10 kHz to 1 MHz). Power supply rejection ratio reaches 90 dB from 200 Hz to 200 kHz. Quiescent current is 4 mA at no load, dropping to 0.2 µA in shutdown. Initial output accuracy is ±0.5%, with line regulation of 0.02 %/V and load regulation of 0.3 %/A.
Feature Summary
- Ultralow noise architecture optimized for RF applications
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with programmable thresholds
- Stable operation with small ceramic output capacitors
Applications
- PLLs and VCOs requiring clean power supplies
- Communications infrastructure equipment
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the ARDZ designation matches the required SOIC package and industrial temperature grade. Ensure the -3.3 variant aligns with the target circuit voltage requirements. Cross-reference the manufacturer part number against official Analog Devices documentation to avoid counterfeit components.
Selection Notes
Select this component for designs demanding minimal output noise and high PSRR in compact form factors. The fixed 3.3 V output eliminates external resistor networks. Verify that the input voltage remains within the 2.3 V to 5.5 V range under all operating conditions. Consider thermal dissipation capabilities given the 600 mA maximum load current capability in the specified package.
Part Context
This part belongs to the ADM7154 family of 600 mA ultra-low noise linear regulators. It shares architectural similarities with the adjustable ADM7155 but offers a fixed output option. The series targets radio frequency applications where signal integrity is critical. Other variants in the family provide different output voltages or adjustable configurations.
Replacement Considerations
The ADM7154ACPZ-3.3-R7 serves as a commercial grade alternative with identical electrical specifications but potentially different temperature ratings. The ADM7154RD-1.8EVALZ is an evaluation board, not a direct replacement. No other direct pin-compatible substitutes are documented in the provided source material.
