Overview
The ADP7156ARDZ-2.5-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 2.5 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 characteristics, including 0.9 µV rms integrated noise (100 Hz to 100 kHz) and high power supply rejection ratio (PSRR). The device achieves a typical dropout voltage of 120 mV at full load and maintains initial accuracy within ±0.6%. Designed for RF applications, it supports stable operation with 10 µF ceramic capacitors and includes precision enable functionality.
Feature Summary
- Ultralow noise architecture optimized for sensitive RF circuits
- High power supply rejection ratio across wide frequency bands
- Precision enable pin with defined logic thresholds
- Stable operation using standard ceramic output capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific suffix R7 indicates reel packaging when sourcing. Confirm the ARDZ designation corresponds to the automotive-grade temperature range and package type required for your design. Ensure compatibility with the 10-lead LFCSP or 8-lead SOIC footprint during PCB layout planning.
Selection Notes
Select this component for designs requiring low noise regulation under heavy loads up to 1.2 A. Consider the 2.5 V fixed output if other voltage options are unsuitable. Evaluate thermal performance based on the junction-to-ambient resistance of the chosen package. Verify that input voltage remains above the minimum operating threshold under all conditions.
Part Context
This part belongs to the ADP7156 family of ultralow noise linear regulators designed for radio frequency applications. It shares architectural similarities with the ADP7157 and ADP7158 series but offers distinct current capabilities and noise specifications tailored for compact RF power solutions.
Replacement Considerations
Direct substitutes include the ADP7157 and ADP7158 for higher current needs, or ADM7150/ADM7151 for higher input voltage ranges. Verify pinout compatibility and thermal requirements before swapping.
