Overview
The ADP7156ARDZ-3.0-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 3.0 V output with a maximum load current of 1.2 A. 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 high power supply rejection ratio (PSRR). The device includes precision enable functionality, low shutdown current, and thermal protection, ensuring stable operation in compact surface-mount packages.
Feature Summary
- Ultralow noise architecture optimized for RF applications
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with defined logic thresholds
- Stable operation with standard ceramic output capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R7 against official documentation to confirm reel packaging specifications. Ensure the 3.0 V fixed output variant matches the design requirement, as other voltages exist within the family. Confirm automotive qualification status if required for the target application environment.
Selection Notes
Select this component when ultralow noise and high PSRR are critical for sensitive RF circuits. Verify that the 1.2 A current capability meets peak load demands. Consider the 8-lead SOIC or 10-lead LFCSP package options based on available PCB real estate and thermal dissipation requirements.
Part Context
This part belongs to the ADP7156 series of linear regulators designed for radio frequency applications. It shares architectural similarities with related devices like the ADP7157 and ADM7150 but offers distinct current and voltage characteristics tailored for high-performance noise-sensitive systems.
Replacement Considerations
Consult official cross-reference lists for verified substitutes. Direct replacements must match the 1.2 A current rating, 3.0 V output, and compatible package footprint.
