Overview
The ADP7158ACPZ-2.0-R7 is a fixed-output linear regulator from Analog Devices, providing a precise 2.0 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 utilizes a 10-lead LFCSP package and includes precision enable functionality.
Feature Summary
- Delivers high power supply rejection and ultralow noise for sensitive RF applications
- Optimized for stability using only a 10 µF ceramic output capacitor
- Features programmable precision enable thresholds with internal discharge resistors
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 2.0 V fixed output variant matches the design requirement. Check for moisture sensitivity levels and ensure proper ESD handling protocols are followed during assembly due to the surface-mount nature of the component.
Selection Notes
Select this component for designs requiring high current capability alongside strict noise constraints. Ensure the input voltage remains above the minimum threshold while accounting for dropout voltage at full load. Verify that the PCB layout supports the thermal requirements of the LFCSP package for sustained 2 A operation.
Part Context
This part belongs to the ADP7158 family of high PSRR RF linear regulators. It is distinguished from adjustable variants like the ADP7159 by its fixed 2.0 V output. The device shares architectural similarities with the ADM7150 series but offers higher current capacity in a compact footprint suitable for dense board layouts.
Replacement Considerations
Direct functional substitutes include the ADP7159 for adjustable output needs or the ADM7150/ADM7151 for lower current applications. Cross-referencing pinouts and thermal characteristics is essential when transitioning between these related regulator families.
