ADP5037ACPZ-R7

Overview

The ADP5037ACPZ-R7 is a four-output switching voltage regulator from Analog Devices, featuring two synchronous buck converters and two low-dropout linear regulators. It operates within an input voltage range of 2.3 V to 5.5 V. The buck channels provide adjustable output voltages with current ratings of 800 mA and 300 mA respectively. The device integrates a 3 MHz switching frequency and maintains a typical quiescent current of 10 uA. It supports load regulation of -0.1%/A and functions reliably across an extended temperature range from -40°C to +125°C.

Feature Summary

• Integrates dual synchronous buck regulators and dual LDOs in a single package for comprehensive power management
• Features high switching frequency operation to minimize external passive component size
• Provides ultra-low static current consumption for efficient battery-powered applications
• Includes undervoltage lockout protection to ensure stable startup and operation

Applications

• Portable consumer electronics requiring multiple voltage rails
• Industrial control systems with space-constrained power designs
• Battery-operated devices needing extended runtime efficiency
• Embedded computing modules requiring compact PMIC solutions

Procurement Notes

Verify the specific suffix R7 indicates reel packaging when sourcing components. Confirm that the ACPZ designation corresponds to the LFCSP-24 package variant suitable for surface mount assembly. Ensure compatibility with standard reflow soldering profiles for lead-free processes. Check manufacturer documentation for moisture sensitivity level requirements prior to handling. Validate that the part number matches the exact electrical specifications required for the target circuit design.

Selection Notes

Select this component when a compact solution combining both switching and linear regulation is necessary. Consider the 800 mA and 300 mA output capabilities against total system load requirements. Evaluate the 3 MHz frequency trade-off between component size and electromagnetic interference. Assess the 2.3 V minimum input voltage against the lowest expected supply rail conditions. Review thermal performance data for the LFCSP-24 package under maximum load scenarios.

Part Context

This part belongs to the ADP5037 series of multi-output power management integrated circuits. It complements other Analog Devices regulators by offering a mixed topology approach. The series targets applications demanding high integration density. Related parts may offer different current ratings or fixed output voltages. The ADP5037 specifically addresses needs for flexible voltage adjustment across multiple rails.

Replacement Considerations

Consult official cross-reference lists for direct functional equivalents. Verify pin-to-pin compatibility if substituting in existing layouts. Compare electrical parameters such as current limits and switching frequencies carefully.
