Overview
The ADM7154ARDZ-2.8-R7 is a fixed-output linear regulator providing 2.8 V at up to 600 mA load current. It operates from an input voltage range of 2.3 V to 5.5 V with 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%. It includes precision enable control, 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 pin with internal hysteresis
- Integrated thermal and current overload protection
Applications
- PLLs and VCOs requiring clean power regulation
- Communications infrastructure equipment
- Backhaul and microwave links
Procurement Notes
Verify the specific ordering suffix R7 corresponds to the required reel packaging configuration before procurement. Confirm that the ARDZ variant meets the necessary industrial temperature specifications for the intended deployment environment. Ensure compatibility with the ADIsimPower design tool for final validation of component selection against system constraints.
Selection Notes
Select this component when low noise and high PSRR are critical for sensitive RF circuits. Ensure the input voltage remains within the 2.3 V to 5.5 V range while maintaining sufficient headroom above the 2.8 V output. Verify that the PCB layout supports the recommended 10 µF ceramic output capacitor to guarantee stability and optimal transient response under varying load conditions.
Part Context
This part belongs to the ADM7154 family of 600 mA linear regulators designed for radio frequency applications. It shares architectural similarities with the adjustable ADM7155 but provides a fixed 2.8 V output. The device utilizes an advanced proprietary architecture to achieve superior line and load transient responses compared to standard LDOs, making it suitable for compact, high-performance power management solutions.
Replacement Considerations
The ADM7154ACPZ-2.8-R7 serves as a commercial grade alternative offering identical electrical performance. For adjustable output requirements within the same package and current class, the ADM7155 series provides a compatible functional replacement.
