MIC5373-MG4YMT-TR

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

The MIC5373-MG4YMT-TR is a triple-output linear regulator featuring three independent 200mA LDOs in a 16-pin 2.5mm x 2.5mm Thin MLF package. It provides fixed output voltages of 2.8V, 1.8V, and 1.2V with ±2% accuracy. The device operates from an input voltage range of 1.7V to 5.5V and includes active-high enable pins for each channel. Integrated features include a power-on-reset supervisor with adjustable delay, manual reset capability, current limit protection, and thermal shutdown.

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

Verify the specific suffix MG4YMT to confirm the 2.8V/1.8V/1.2V output configuration. Confirm the manufacturer origin as Micrel or Microchip Technology due to acquisition history. Ensure the component is sourced from authorized distributors to guarantee authenticity and proper handling of ESD-sensitive materials.

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

Select this part when multiple regulated rails are required in a compact footprint. The MIC5373 variant is chosen over the MIC5383 specifically for its active-high enable logic. Verify that the application requires fixed voltage outputs rather than adjustable ones. Ensure the design accommodates the necessary external capacitors for stability and POR timing.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Part Context

This component belongs to the MIC5373/83 family of µCap LDO regulators designed for mobile platforms. It shares the same physical package and core architecture with the MIC5383, differing primarily in the polarity of the enable inputs. The series is engineered to support application processors while minimizing board space through its tiny MLF packaging.

Voltage Regulators - Linear, Low Drop Out (LDO) Regulators Replacement Considerations

MIC5383-MG4YMT-TR is a functional substitute with identical electrical parameters but utilizes active-low enables instead of active-high.
