Overview
The ADP7156ACPZ-2.8-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 2.8 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 from 100 Hz to 100 kHz. The device delivers high power supply rejection ratio (PSRR) performance, achieving 80 dB from 1 kHz to 100 kHz. It incorporates precision enable functionality, low shutdown current, and thermal protection mechanisms.
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 ordering suffix against official documentation to confirm package type and tape-and-reel specifications. Confirm that the component meets required automotive or industrial qualification standards if applicable. Ensure compatibility with existing PCB footprints and thermal management designs before finalizing procurement orders.
Selection Notes
Select this regulator when designing circuits requiring minimal output noise and high PSRR for sensitive RF components. Consider the 10-lead LFCSP package for compact layouts and efficient thermal dissipation. Evaluate input voltage headroom requirements relative to the dropout voltage at expected load currents to ensure stable regulation under all operating conditions.
Part Context
This component belongs to the ADP7156 family of high-performance linear regulators designed for radio frequency systems. It shares architectural similarities with related devices like the ADP7157 and ADP7158 but offers distinct current capabilities and output voltage options. The series emphasizes stability with small ceramic capacitors and includes advanced features such as programmable enable and thermal shutdown.
Replacement Considerations
Direct substitutes include other ADP7156 variants with different fixed output voltages, such as ADP7156ACPZ-2.5-R7 or ADP7156ACPZ-3.3-R7, provided the system voltage requirement changes. For higher current needs, consider the ADP7158 family.
