MAX5092AATE+

Overview

The MAX5092AATE+ is an ultrahigh current, ultralow dropout voltage regulator featuring a boost preregulator. It accepts input voltages from 4V to 72V and provides an adjustable output up to 36V with a maximum current of 250mA. The device operates at a fixed 1MHz switching frequency and includes internal current limiting. It is housed in a 16-pin TQFN package and supports operation temperatures up to +125°C.

Feature Summary

• Integrates a boost preregulator to maintain low dropout voltage across wide input ranges
• Supports high input voltages up to 72V for robust power supply applications
• Provides adjustable output voltage with precise regulation capabilities

Applications

• Ultrahigh current ultralow dropout regulator circuits
• High-current, current-limited switch implementations
• Video cassette recorder (VCR) power systems

Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm pinout and thermal specifications. Ensure the procurement channel provides genuine components with traceable manufacturing dates. Cross-reference the datasheet revision date to validate technical parameters before integration into design projects.

Selection Notes

Select this component when designing systems requiring stable regulation from high-voltage inputs exceeding standard LDO limits. The integrated boost preregulator allows for efficient operation even when input voltage approaches the output level. Consider the 16-pin TQFN package constraints for thermal management in compact layouts.

Part Context

This device belongs to the Maxim Integrated line of high-performance analog regulators. It combines linear regulation precision with the efficiency benefits of a pre-regulation stage. The series is designed for demanding industrial and consumer applications requiring reliable power delivery under varying load conditions.

Replacement Considerations

Check for direct pin-compatible alternatives within the same product family that may offer updated thermal performance or different output current ratings. Verify that any substitute maintains the 72V input capability and 1MHz switching frequency requirements.
