Overview
The ADM7154ARDZ-3.0-R7 is a fixed-output linear regulator providing 3.0 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, specified as 0.9 µV rms (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%. It is housed in an 8-lead LFCSP package.
Feature Summary
- Ultralow noise performance optimized for RF applications
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with programmable thresholds
- Internal thermal overload and current-limit protection
Applications
- PLLs and VCOs requiring clean power regulation
- 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 industrial temperature grade and SOIC/LFCSP availability. Ensure the 3.0 V fixed output variant is explicitly selected during procurement to avoid confusion with adjustable or other fixed voltage options within the ADM7154 family.
Selection Notes
Select this component for designs requiring high PSRR and minimal output noise without external filtering components. Ensure input voltage remains above the minimum operating threshold while accounting for dropout voltage under maximum load conditions. Verify that the 10 µF ceramic output capacitor requirement aligns with board space constraints. Consider thermal dissipation limits if operating near maximum junction temperatures.
Part Context
This part belongs to the ADM7154 series of 600 mA ultralow noise linear regulators. It shares architectural similarities with the ADM7155 but offers fixed output voltages instead of adjustable options. The device targets radio frequency applications where power supply integrity is critical. It complements Analog Devices' portfolio of precision power management solutions for sensitive analog circuits.
Replacement Considerations
The ADM7154ACPZ-3.0-R7 serves as a commercial grade alternative with identical electrical specifications. The ADM7155 series provides adjustable output variants with comparable performance metrics. Cross-reference package dimensions and pinouts when substituting to ensure mechanical compatibility.
