ADP7159ACPZ-04-R7

Overview

The ADP7159ACPZ-04-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 3.3 V with high power supply rejection ratio (PSRR) and ultralow noise characteristics. The device features a typical dropout voltage of 200 mV at full load and maintains initial accuracy of ±0.6%. It operates reliably across a temperature range of -40°C to +125°C and utilizes a 10-lead LFCSP package.

Feature Summary

Ultralow noise performance optimized for RF applications
High power supply rejection ratio across wide frequency bands
Precision enable pin with defined logic thresholds
Stable operation with small ceramic output capacitors

Applications

Phase-locked loops (PLLs)
Voltage controlled oscillators (VCOs)
Backhaul and microwave links

Procurement Notes

Verify the specific suffix '-04' corresponds to the required input/output voltage optimization for your design. Confirm the LFCSP-10 package footprint matches your PCB layout. Check for moisture sensitivity levels and reflow soldering profiles before assembly. Ensure the ordering part number includes the '-R7' tape and reel designation if automated placement is required.

Selection Notes

Select this model when input voltages are between 3.8 V and 5.5 V and output requirements are near 3.3 V to minimize power dissipation. Consider the thermal resistance of the LFCSP package for high-current applications. Evaluate the need for external bypass capacitors on the BYP pin to further reduce low-frequency noise if necessary for sensitive analog circuits.

Part Context

This component belongs to the ADP7159 family of RF linear regulators designed for noise-sensitive systems. It shares architectural similarities with the ADP7157 and ADP7158 but offers higher current capability. The family provides fixed and adjustable options to optimize efficiency based on specific voltage headroom requirements in communication infrastructure.
