Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC5322-MGYMT-TR are qualified based on the following critical parameters that determine functional equivalence:

Electrical Matching Criteria:

• Output voltage configuration: Positive Fixed, dual 1.8V/2.8V outputs
• Maximum input voltage: 5.5V
• Output current capability: 150mA per channel
• Operating temperature range: -40°C ~ 125°C
• Protection features: Over Current and Over Temperature protection
• Control features: Enable function

Mechanical & Packaging Criteria:

• Package type: 6-TMLF® (1.6x1.6) Surface Mount
• Mounting type: Surface Mount
• Physical footprint compatibility

Regulatory & Compliance Criteria:

• RoHS3 Compliance
• Moisture Sensitivity Level 1
• REACH Unaffected status
• Active product status

The MIC5370-MGYMT-TR and MIC5371-MGYMT-TR meet all core electrical and mechanical requirements for direct substitution. Differences in quiescent current, dropout voltage, and PSRR performance are secondary parameters that do not prevent functional equivalence in standard applications.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MIC5322-MGYMT-TR, MIC5370-MGYMT-TR, and MIC5371-MGYMT-TR—are actively manufactured by Microchip Technology and maintain full ROHS3 compliance with MSL 1 rating. Selection between these parts should be based on application-specific requirements:

MIC5322-MGYMT-TR is the primary choice when lowest dropout voltage (0.1V @ 150mA) is critical for maintaining output voltage stability under maximum load conditions, or when minimizing quiescent current is not a design constraint.

MIC5370-MGYMT-TR and MIC5371-MGYMT-TR are functionally equivalent alternatives offering improved quiescent current performance (45 µA versus 190 µA), making them suitable for battery-powered or low-power standby applications where reduced idle power consumption is beneficial. The higher dropout voltage (0.31V @ 150mA) remains within acceptable limits for most standard applications.

All parts share identical output voltage configuration, current capability, operating temperature range, and protection features, ensuring direct functional substitution in circuit designs without modification to supporting component values or PCB layout.

Frequently Asked Questions (FAQ)

Q: Can MIC5370-MGYMT-TR or MIC5371-MGYMT-TR be used as direct replacements for MIC5322-MGYMT-TR?

A: Yes. Both parts deliver the same dual fixed output voltages (1.8V and 2.8V) at 150mA per channel with identical package geometry (6-TMLF®), operating temperature range, and protection features. The primary difference is dropout voltage performance; applications tolerant of 0.31V dropout can use these substitutes without circuit modification.

Q: What is the significance of the dropout voltage difference between these parts?

A: Dropout voltage determines the minimum input-to-output voltage differential required to maintain regulation. MIC5322-MGYMT-TR requires 0.1V headroom, while MIC5370-MGYMT-TR and MIC5371-MGYMT-TR require 0.31V. In applications with tight input voltage margins, the lower dropout of MIC5322-MGYMT-TR may be necessary. For standard applications with adequate input voltage margin, the higher dropout is not a limiting factor.

Q: Are there packaging differences between these parts?

A: MIC5322-MGYMT-TR and MIC5370-MGYMT-TR are supplied in Tape & Reel (TR) packaging. MIC5371-MGYMT-TR is available in both Cut Tape (CT) and Digi-Reel® formats, though the core 6-TMLF® package remains identical. All three parts are Surface Mount components with the same footprint and land pattern.

Q: Which part offers the best power efficiency for low-power applications?

A: MIC5370-MGYMT-TR and MIC5371-MGYMT-TR both feature 45 µA quiescent current, compared to 190 µA for MIC5322-MGYMT-TR. For battery-powered or always-on standby circuits, the lower quiescent current of MIC5370 and MIC5371 variants reduces idle power consumption and extends battery life.

Q: Are all three parts RoHS compliant?

A: Yes. MIC5322-MGYMT-TR, MIC5370-MGYMT-TR, and MIC5371-MGYMT-TR are all ROHS3 compliant with MSL 1 rating and REACH Unaffected status, meeting current environmental and regulatory requirements for commercial and industrial applications.
