MIC5239-2.5YMM-TR

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Overview

The MIC5239-2.5YMM-TR is a fixed-output low-dropout linear regulator manufactured by Microchip Technology, providing a stable 2.5V output with a maximum current capacity of 500mA. It operates within an input voltage range of 2.3V to 30V and features a typical dropout voltage of 350mV at full load. The device utilizes an MSOP-8 surface-mount package and includes integrated protection mechanisms such as thermal shutdown and current limiting. Designed for high-voltage battery applications, it maintains a low quiescent current to ensure efficient power management in space-constrained systems.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Procurement Notes

Verify the specific suffix 'YMM' corresponds to the MSOP-8 package and tape-and-reel delivery format. Confirm that the fixed 2.5V output rating matches the target circuit requirements. Ensure compatibility with RoHS standards if required by the manufacturing process. Check for any recent product change notices regarding pinout or electrical specifications before finalizing procurement.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Selection Notes

Select this component when a fixed 2.5V rail is needed from a higher voltage source up to 30V. It is appropriate for designs prioritizing low external component count due to its µCap stability. Consider the MSOP-8 package size relative to available PCB real estate. Evaluate thermal performance based on the expected voltage drop and load current to ensure junction temperatures remain within safe operating limits.
