MIC5528-2.8YMX-TR Equivalent & Substitute Parts

Part Overview

The MIC5528-2.8YMX-TR is a linear voltage regulator IC from Microchip Technology designed for power management applications. This positive fixed output regulator delivers 500mA at 2.8V with a maximum dropout voltage of 0.5V at full load. The device is currently in active production status and is widely used in battery-powered and low-voltage applications requiring stable regulated output with integrated protection features.

Identifying equivalent and substitute parts is necessary when the primary part number becomes unavailable, when supply chain constraints occur, or when design flexibility is required for component sourcing across multiple suppliers or manufacturing locations.

Substitute Part Grouping Explanation

Substitution for the MIC5528-2.8YMX-TR is determined by strict equivalence across the following critical parameters:

• Fixed output voltage of 2.8V
• Minimum output current capability of 500mA
• Maximum input voltage rating of 5.5V or higher
• Maximum dropout voltage of 0.5V or lower at 500mA
• Positive output configuration
• Surface mount packaging in 6-XFDFN form factor with exposed pad
• Operating temperature range of -40°C to 125°C or wider
• Active product status
• RoHS3 compliance

Only parts meeting all of these specifications are considered true parametric equivalents. The MIC5528-2.8YMX-TR serves as both the primary part and its own direct equivalent within this product line.

Parameter Comparison

Engineering Selection Recommendations

The MIC5528-2.8YMX-TR is an active product with full RoHS3 compliance and REACH unaffected status, making it suitable for current design implementations and long-term production use. When sourcing this component, verify that replacement parts maintain identical electrical specifications, particularly the 2.8V fixed output voltage, 500mA current rating, and 0.5V maximum dropout voltage at full load.

The 6-XFDFN package with exposed pad is critical for thermal management in applications requiring sustained 500mA output. PCB layout and thermal design must account for the specified package dimensions of 1.2mm × 1.2mm.

Component selection should prioritize parts with active product status and current manufacturing support to ensure long-term availability and consistent quality across production batches.

Frequently Asked Questions (FAQ)

Q: What makes a part a true substitute for the MIC5528-2.8YMX-TR?

A: A substitute must match all critical electrical parameters: 2.8V fixed output voltage, 500mA output current capability, 5.5V maximum input voltage, 0.5V maximum dropout voltage at 500mA, positive output configuration, and the same 6-XFDFN surface mount package with exposed pad. The operating temperature range must cover -40°C to 125°C.

Q: Can I use a different output voltage regulator as a substitute?

A: No. The fixed 2.8V output voltage is application-specific. Using a regulator with a different output voltage will cause circuit malfunction. Only parts with identical 2.8V output specifications are acceptable substitutes.

Q: Is the package size critical for substitution?

A: Yes. The 6-XFDFN (1.2mm × 1.2mm) package with exposed pad is mandatory for PCB compatibility and thermal performance. Different package types or sizes are not interchangeable without redesigning the PCB layout.

Q: What is the significance of the exposed pad in the 6-XFDFN package?

A: The exposed pad provides a thermal connection to the PCB ground plane, enabling efficient heat dissipation during sustained 500mA operation. This is essential for maintaining the specified dropout voltage performance and device reliability.

Q: Does RoHS3 compliance affect substitution eligibility?

A: Yes. Both the main part and any substitute must maintain RoHS3 compliance for applications requiring regulatory adherence. This certification status is non-negotiable for qualified component selection.

Q: Can I substitute based on similar electrical characteristics from a different manufacturer?

A: No. Substitution must be based on exact parametric matching of all specified electrical and mechanical characteristics. Similar performance from alternative manufacturers does not constitute a valid substitute unless all parameters are identical.
