ADP5074ACPZ-R7

Overview

The ADP5074ACPZ-R7 is a high-efficiency DC-DC switching inverting regulator manufactured by Analog Devices Inc. It operates within an input voltage range of 2.85 V to 15 V and delivers an adjustable output current up to 2.4 A. The device features a switch frequency range of 1.2 MHz to 2.4 MHz and maintains a typical quiescent current of 1.8 mA. Designed for robust performance, it supports an operating temperature range from -40 °C to +125 °C. The component is housed in a compact LFCSP-16 package suitable for surface mount applications.

Feature Summary

• Provides negative voltage generation through an inverting topology
• Supports wide input voltage ranges for flexible power supply integration
• Features adjustable output voltage control via external feedback components

Applications

• Powering bipolar analog-to-digital converters requiring dual rails
• Supplying operational amplifiers with negative bias voltages
• Generating auxiliary negative supplies for mixed-signal systems

Procurement Notes

Verify the specific suffix R7 indicates reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to implementation. Ensure compatibility with available evaluation tools such as the ADP5074CP-EVALZ for initial circuit validation. Check for moisture sensitivity level requirements during storage and handling procedures.

Selection Notes

Select this component when a single-inductor inverting solution is required for moderate current loads. Compare against the ADP5073 if lower output current specifications are sufficient for the design. Consider the ADP5071 if simultaneous positive and negative rail generation is necessary instead of inversion only. Evaluate thermal dissipation capabilities based on the LFCSP-16 package limitations.

Part Context

This part belongs to the ADP507x series of ultra-low noise switching regulators designed for precision analog applications. The series focuses on minimizing output ripple while maintaining high efficiency in compact footprints. These regulators are commonly integrated into data acquisition systems and industrial instrumentation where clean power supplies are critical for signal integrity.

Replacement Considerations

The ADP5073ACPZ-R7 serves as a direct functional substitute with identical pinout but reduced output current capability.
