Overview
The ADM7154ACPZ-2.8-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 2.8 V output with a maximum load current of 600 mA. It operates within an input voltage range of 2.3 V to 5.5 V and features ultralow noise performance, characterized by 0.9 µV rms integrated noise (100 Hz to 100 kHz) and 1.5 nV/√Hz spectral density (10 kHz to 1 MHz). The device achieves high power supply rejection ratios of 90 dB (200 Hz to 200 kHz) and 58 dB at 1 MHz. Quiescent current is 4 mA at no load, dropping to 0.2 µA in shutdown mode. It includes precision enable functionality, thermal overload protection, and current limiting.
Feature Summary
- Ultralow noise architecture optimized for RF applications using proprietary filtering
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with programmable thresholds and hysteresis
- Stable operation with standard ceramic capacitors
Applications
- PLLs and VCOs requiring low-noise regulation
- Communications infrastructure equipment
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix -R7 indicates reel packaging when sourcing. Confirm the 2.8 V fixed output variant matches the design requirement. Check datasheet revision C for updated outline dimensions. Ensure ESD precautions are followed during handling due to sensitivity.
Selection Notes
Select this component for designs requiring strict noise suppression in RF signal chains. Verify that the input voltage remains above the dropout threshold under all load conditions. Consider the 8-lead LFCSP package for compact layouts. Evaluate PCB thermal resistance if operating near maximum current limits.
Part Context
This part belongs to the ADM7154 family of 600 mA ultralow noise linear regulators. It shares architectural similarities with the adjustable ADM7155 but offers fixed voltage options. The series targets high-performance analog circuits where power supply integrity directly impacts signal fidelity.
Replacement Considerations
The ADM7154ACPZ-3.3-R7 provides identical electrical characteristics except for a fixed 3.3 V output. The ADM7155 series offers adjustable output voltages with similar noise and PSRR specifications.
