Overview
The ADM7154ACPZ-1.8-R7 is a fixed-output linear regulator providing 1.8 V at up to 600 mA load current. It operates from an input voltage range of 2.3 V to 5.5 V with typical quiescent current of 4 mA and shutdown current of 0.2 µA. 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. Initial output accuracy is ±0.5%, with dropout voltage typically 120 mV at 600 mA. It includes precision enable, thermal overload protection, and current limiting.
Feature Summary
- Ultralow noise architecture optimized for RF applications
- High power supply rejection ratio across wide frequency ranges
- Precision programmable enable threshold with hysteresis
- Integrated thermal overload and current-limit protection
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 confirming order details. Ensure the 1.8 V fixed output variant matches the system requirement. Confirm the LFCSP package type aligns with PCB footprint specifications. Check for any RoHS compliance documentation if required by manufacturing standards.
Selection Notes
Select this component for designs requiring high PSRR and minimal output noise in compact form factors. The 1.8 V fixed output eliminates external resistor networks. Ensure input voltage remains above 2.3 V and below 5.5 V. Verify that the 10 µF ceramic output capacitor requirement fits within the board area constraints.
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 1.8 V output. The device is designed for radio frequency applications where signal integrity is critical. It utilizes an 8-lead LFCSP package for efficient thermal dissipation.
Replacement Considerations
The ADM7155ACPZ-1.8-R7 provides the same electrical characteristics but features an adjustable output voltage instead of a fixed 1.8 V setting. Designers must verify if the fixed output constraint is necessary or if adjustability is preferred.
