MIC5159-1.8BM5 TR

Overview

The MIC5159-1.8BM5 TR is a linear regulator controller manufactured by Microchip Technology, designed for single-output applications. It operates within an input voltage range of 3V to 36V and supports fixed or adjustable output configurations. The device features a supply current of 4.5mA and functions reliably across a temperature range of -40°C to 85°C. Packaged in a compact SOT23-5 format, it integrates essential protection mechanisms including thermal shutdown and overcurrent limiting to ensure stable performance in power management systems.

Feature Summary

• Supports wide input voltage range from 3V to 36V
• Integrates thermal shutdown and overcurrent protection
• Enables fixed or adjustable output regulation

Applications

• Battery-powered portable electronics
• Industrial control systems
• Communication equipment power supplies

Procurement Notes

Verify the specific suffix BM5 corresponds to the SOT23-5 package configuration when sourcing. Confirm that the TR designation indicates tape and reel packaging suitable for automated assembly processes. Ensure compatibility with existing PCB footprints before finalizing procurement decisions.

Selection Notes

Select this component for designs requiring high input voltage tolerance with low quiescent current consumption. The SOT23-5 package offers space efficiency for dense layouts. Consider the operating temperature range limits when deploying in extreme environmental conditions compared to industrial-grade alternatives.

Part Context

This part belongs to the MIC5159 family of linear regulator controllers, which are engineered for driving external pass transistors. Unlike integrated LDOs, these controllers provide flexibility in selecting output devices to meet specific current and voltage requirements while maintaining precise regulation characteristics.

Replacement Considerations

Direct substitutes include other variants within the MIC5159 series such as MIC5159YM6-TR for different package options. Verify pinout compatibility and electrical specifications before substituting with generic linear regulator controllers.
