MIC5366-2.85YMT-TZ Equivalent & Substitute Parts

Part Overview

The MIC5366-2.85YMT-TZ is a linear voltage regulator IC from Microchip Technology, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 2.85V at 150mA with a maximum dropout voltage of 0.31V at rated current. The device is actively produced and widely used in applications requiring low-noise, low-dropout regulation in compact form factors. Substitute parts are identified to address inventory availability, extended temperature range requirements, or alternative packaging preferences while maintaining functional equivalence.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC5366-2.85YMT-TZ are qualified based on the following electrical and mechanical parameters:

Core Substitution Criteria:

• Fixed output voltage of 2.85V
• Output current rating of 150mA
• Maximum input voltage of 5.5V
• Surface mount packaging with exposed pad configuration
• Enable control feature
• Over current and over temperature protection
• Active product status
• ROHS3 compliance

The identified substitutes (TLV717285PDQNR and TLV717285PDQNT from Texas Instruments) meet these core criteria. Both parts are functionally equivalent linear voltage regulators with identical output specifications and input voltage ratings. Differences exist in dropout voltage performance (0.35V vs. 0.31V), quiescent current (55 µA vs. 39 µA), PSRR characteristics, and operating temperature range (-40°C ~ 85°C vs. -40°C ~ 125°C). Package form factors differ (4-X2SON vs. 4-TMLF®), requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

Selection between the MIC5366-2.85YMT-TZ and its substitutes depends on application-specific constraints:

MIC5366-2.85YMT-TZ is the primary choice for applications requiring extended operating temperature range to 125°C, lower quiescent current (39 µA), and superior PSRR performance at mid-frequency ranges (1kHz ~ 10kHz). The 4-TMLF® package is established in existing designs.

TLV717285PDQNR and TLV717285PDQNT are functionally equivalent alternatives when the operating temperature range of -40°C ~ 85°C is acceptable. Both Texas Instruments parts provide additional protection features (short circuit protection and UVLO) not present in the Microchip device. The 4-X2SON package requires PCB layout modification. TLV717285PDQNR and TLV717285PDQNT differ only in packaging designation (reel vs. tape format) and inventory availability; electrical performance is identical.

All three parts maintain ROHS3 compliance, unlimited moisture sensitivity rating (MSL 1), and active product status, ensuring long-term supply chain viability.

Frequently Asked Questions (FAQ)

Q: Can TLV717285PDQNR or TLV717285PDQNT be used as direct replacements for MIC5366-2.85YMT-TZ?

A: Electrical substitution is valid when the operating temperature range of -40°C ~ 85°C meets application requirements. The 4-X2SON package differs from 4-TMLF®, requiring PCB layout verification for pin placement, thermal pad dimensions, and trace routing. Functional performance is equivalent for the specified output voltage (2.85V) and current (150mA).

Q: What are the key differences between MIC5366-2.85YMT-TZ and TLV717285PDQNR/PDQNT?

A: The primary differences are: (1) operating temperature range (125°C vs. 85°C maximum), (2) quiescent current (39 µA vs. 55 µA), (3) dropout voltage (0.31V vs. 0.35V at 150mA), (4) PSRR characteristics across frequency ranges, (5) additional protection features in Texas Instruments parts (short circuit, UVLO), and (6) package form factor (4-TMLF® vs. 4-X2SON).

Q: Is there a difference between TLV717285PDQNR and TLV717285PDQNT?

A: Both parts are electrically and functionally identical. The suffix designates packaging format: PDQNR indicates reel packaging, while PDQNT indicates tape packaging. Selection depends on assembly equipment compatibility and inventory management preferences.

Q: What happens if my application requires operation above 85°C?

A: The MIC5366-2.85YMT-TZ supports continuous operation to 125°C and is the required choice for high-temperature applications. Texas Instruments substitutes are limited to 85°C maximum junction temperature and are not suitable for extended temperature operation.

Q: Are all three parts RoHS compliant?

A: Yes. MIC5366-2.85YMT-TZ, TLV717285PDQNR, and TLV717285PDQNT are all ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing processes and long-term environmental compliance.

Q: How do I verify PCB compatibility when switching from 4-TMLF® to 4-X2SON packaging?

A: Consult the respective datasheets for thermal pad dimensions, pin pitch, and exposed pad specifications. The 4-X2SON package may have different thermal characteristics and land pattern requirements. PCB layout must be verified before production implementation.
