MIC5208-3.8YMM-TR

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

The MIC5208-3.8YMM-TR is a low-dropout linear voltage regulator manufactured by Microchip Technology, featuring a fixed 3.8V output and a 150mA maximum load current capability. It operates within an input voltage range of 2.7V to 6V and maintains a typical dropout voltage of 240mV at full load. The device incorporates a power-good flag for system monitoring and includes comprehensive protection mechanisms such as overcurrent limiting, thermal shutdown, and reverse battery protection. Designed for surface-mount applications, it utilizes a compact 6-pin SOT-23 package and supports operation across an extended industrial temperature range from -40°C to +125°C.

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

Verify the specific suffix YMM corresponds to the required tape-and-reel packaging configuration before ordering. Confirm that the fixed 3.8V output aligns precisely with the target circuit design requirements. Ensure compatibility with the specified SOT-23 footprint during PCB layout validation. Cross-reference the manufacturer's latest datasheet for any updates regarding pin assignments or electrical characteristics prior to final procurement decisions.

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

Select this component when a fixed 3.8V output is strictly required rather than adjustable variants. Consider the 150mA current limit sufficient for the intended load while evaluating the 240mV dropout voltage against minimum input supply levels. The inclusion of a power-good flag makes it suitable for systems requiring precise power sequencing or fault detection. Verify that the operating temperature range meets the environmental demands of the final application.
