Overview
The ADP7158ARDZ-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 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 a typical power supply rejection ratio of 70 dB from 1 kHz to 100 kHz. The device includes precision enable functionality, thermal shutdown protection, and is stable with a 10 µF ceramic output capacitor.
Feature Summary
- Ultralow noise architecture optimized for radio frequency applications
- High power supply rejection ratio across wide frequency ranges
- Precision enable pin with programmable logic thresholds
- Stable operation using standard ceramic capacitors
Applications
- Phase-locked loops (PLLs)
- Voltage controlled oscillators (VCOs)
- Backhaul and microwave links
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape-and-reel configuration. Confirm that the fixed 2.8 V output voltage aligns with the system design requirements. Ensure compatibility with the intended PCB layout regarding thermal dissipation and minimum capacitance specifications.
Selection Notes
Select this component when high current delivery up to 2 A is required alongside stringent noise suppression standards. Consider the available packages, such as the 8-lead SOIC or 10-lead LFCSP, based on space constraints and thermal management needs. Evaluate the need for external bypass capacitors to optimize start-up time versus noise performance.
Part Context
This part belongs to the ADP7158 family of RF linear regulators designed for demanding analog signal integrity. It shares architectural similarities with the ADP7156 and ADP7157 but offers higher current capacity. The series supports various fixed output voltages between 1.2 V and 3.3 V.
Replacement Considerations
The ADP7159 serves as an adjustable output alternative within the same family. For lower current requirements, the ADM7154 or ADM7155 may be considered, though they provide reduced output current capabilities.
