MAX721ESE

Overview

The MAX721ESE+ is a switching regulator manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a buck topology and is housed in an SOIC-16 package for surface mount installation. The device provides a fixed output voltage of 5 V with a maximum output current capability of 500 mA. It features a single output channel and operates within a temperature range of -40°C to +85°C. The component draws a static current of 100 uA during operation.

Feature Summary

• Buck converter topology for step-down voltage regulation
• Fixed 5 V output voltage configuration
• Surface-mount SOIC-16 packaging

Applications

• General-purpose DC-DC power supply circuits
• Embedded system voltage regulation
• Industrial control board power distribution

Procurement Notes

Verify the exact suffix (e.g., ESE+) against official datasheets to confirm pinout and thermal specifications. Confirm availability status as distributors may list limited stock or end-of-life conditions. Ensure the supplier source matches the manufacturer's authorized channels to guarantee component authenticity and traceability.

Selection Notes

Select this component when a fixed 5 V output from a higher input voltage is required in a compact form factor. Consider the 500 mA current limit and buck topology efficiency relative to application needs. Verify that the operating temperature range meets environmental requirements and that the SOIC-16 footprint fits the PCB layout constraints.

Part Context

This part belongs to the Maxim Integrated line of switching regulators, designed for efficient power management in space-constrained applications. The series focuses on providing stable voltage conversion with minimal external components, suitable for integration into various electronic systems requiring reliable DC power sources.

Replacement Considerations

Check for direct cross-reference part numbers from Analog Devices or other manufacturers offering identical buck topology, 5V output, and SOIC-16 package. Verify electrical parameter compatibility before substitution.
