MIC5322-MFYMT

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

The MIC5322-MFYMT is a dual-output ultra-low dropout linear regulator manufactured by Microchip Technology. It provides two independent fixed output voltages of 1.8V and 2.5V, each capable of delivering up to 0.15A. The device operates from an input voltage range of 2.3V to 5.5V. It features a single active-low enable pin controlling both outputs and includes a bypass pin for noise reduction. The component is housed in a compact 6-lead Thin MLF package.

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

Verify the manufacturer designation as Microchip Technology, noting the historical acquisition of Micrel. Confirm the specific suffix MFYMT corresponds to the 1.8V/2.5V output combination. Ensure the package type matches the 6-lead Thin MLF specification. Check for RoHS compliance status if required by your manufacturing standards. Validate that the datasheet references align with the current product line documentation.

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

Select this component when dual isolated LDOs are needed in a minimal footprint. It is suitable for applications requiring 1.8V and 2.5V rails from a single supply. Consider the 0.15A current limit per channel against load requirements. The bypass pin feature is advantageous for noise-sensitive analog circuits. Evaluate thermal performance based on the small package size and expected power dissipation.

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

This part belongs to the MIC5322 family of dual-output LDOs. It shares architectural similarities with other Micrel/Microchip ULDO series but offers specific fixed voltage combinations. The Thin MLF package distinguishes it from larger SOIC or TDFN alternatives. It serves as a compact solution compared to discrete regulator implementations.

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

Check for direct substitutes within the MIC5322 series with different voltage suffixes. Verify compatibility with MIC5322 variants offering different output pairs. Ensure replacement parts maintain the same 6-lead Thin MLF package for board-level interchangeability without layout changes.
