Overview
The ADP7159ARDZ-01-R7 is an adjustable linear regulator from Analog Devices, operating within a 2.3 V to 5.5 V input voltage range and delivering up to 2 A of load current. It provides an output voltage range of 1.2 V to 1.8 V with ultralow noise characteristics, including 1.6 µV rms integrated noise from 10 Hz to 100 kHz. The device features high power supply rejection ratio (PSRR) performance, achieving 55 dB at 1 kHz to 100 kHz and 40 dB at 1 MHz under specified conditions. It maintains initial accuracy of ±0.6% and operates over a temperature range of -40°C to +125°C in a compact 10-lead LFCSP package.
Feature Summary
- Ultralow noise architecture optimized for RF applications
- High power supply rejection ratio across wide frequency bands
- Precision enable function with defined logic thresholds
- Stable operation with standard ceramic output capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Communications infrastructure systems
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix designation against official documentation to confirm the exact output voltage range and package configuration. Confirm thermal requirements and PCB layout guidelines match application constraints. Ensure capacitor selections meet minimum capacitance and ESR specifications for stability. Check for any regional distribution restrictions or availability limitations prior to finalizing procurement plans.
Selection Notes
Select this component when designing circuits requiring low noise regulation for sensitive RF stages. Consider the input-to-output voltage differential to manage power dissipation effectively. Evaluate the required PSRR performance against the specific noise frequencies present in the system. Ensure the chosen package type aligns with available board space and thermal management capabilities.
Part Context
This part belongs to the ADP7159 family of ultralow noise linear regulators designed for radio frequency applications. The series includes variants with different fixed or adjustable output voltage ranges to optimize power dissipation. Related devices include the ADP7158 and ADP7157, offering similar performance profiles with varying current ratings or output configurations.
Replacement Considerations
Consult official Analog Devices documentation for verified substitute part numbers. Cross-reference pinouts and electrical specifications carefully before implementation.
