MIC2212-LPYML-TR Equivalent & Substitute Parts

Part Overview

The MIC2212-LPYML-TR is a linear voltage regulator IC from Microchip Technology designed for power management applications. This dual-output positive fixed regulator operates with input voltages up to 5.5V and delivers fixed output voltages of 2.7V or 3V at current levels of 150mA and 300mA. The device is housed in a 10-MLF® (3x3) surface mount package and is currently in active production status. Substitute parts are identified to address inventory availability, extended lead times, or design flexibility requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MIC2212-LPYML-TR are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Dual-output positive fixed voltage regulator configuration
• Output voltage compatibility (3V output present in both substitutes)
• Current output capability (150mA and 300mA support)
• Surface mount package with 10-pin WFDFN/WSON footprint (3x3mm)
• Exposed pad design for thermal management
• Active product status and RoHS3 compliance

Acceptable Parameter Variations:

• Input voltage maximum: MIC2212-LPYML-TR operates to 5.5V; substitutes operate to 6V (higher rating acceptable)
• Dropout voltage: Substitutes specify 0.22V @ 150mA and 0.55V @ 150mA (within acceptable range for fixed regulator applications)
• Quiescent current: Substitutes at 100 µA versus 80 µA (minimal impact on standby power)
• Operating temperature: Substitutes rated to 85°C versus 125°C (verify application requirements)
• Control features: Substitutes provide Enable function; Power On Reset available in main part only
• Protection features: Substitutes provide Over Temperature and Short Circuit; main part includes Over Current protection

Parameter Comparison

Engineering Selection Recommendations

LP3996SD-3030/NOPB Selection Criteria: This substitute is suitable for applications requiring a fixed 3V output with 150mA or 300mA current delivery. The part maintains active production status and ROHS3 compliance. The 10-WSON package is mechanically compatible with the original 10-MLF footprint. Applications limited to 3V output operation and operating temperatures below 85°C are appropriate for this substitute.

LP3996SD-3033/NOPB Selection Criteria: This substitute provides dual output voltage options (3V and 3.3V), offering greater design flexibility than LP3996SD-3030/NOPB. It maintains the same electrical performance characteristics and package compatibility. Applications requiring either 3V or 3.3V output with operating temperatures below 85°C are appropriate for this substitute.

Temperature Derating Consideration: Both Texas Instruments substitutes are rated to 85°C maximum operating temperature, compared to the MIC2212-LPYML-TR rated to 125°C. Applications requiring operation above 85°C must retain the original Microchip part.

2.7V Output Requirement: The MIC2212-LPYML-TR provides a 2.7V fixed output option not available in the identified substitutes. Applications requiring 2.7V output cannot use these substitutes without design modification.

Frequently Asked Questions (FAQ)

Q: Can LP3996SD-3030/NOPB replace MIC2212-LPYML-TR in all applications? A: No. The LP3996SD-3030/NOPB is suitable only for applications using the 3V output. Applications requiring the 2.7V output option must use the original MIC2212-LPYML-TR. Additionally, applications operating above 85°C ambient temperature require the original part due to its 125°C maximum rating.

Q: What is the package compatibility between 10-MLF and 10-WSON? A: Both packages are 10-pin surface mount devices in 3x3mm form factor with exposed pad design. The footprints are mechanically compatible for PCB layout purposes. Pin assignments and electrical connections must be verified against device datasheets before substitution.

Q: Are there differences in protection features between the main part and substitutes? A: Yes. The MIC2212-LPYML-TR includes Over Current protection, while the LP3996 series provides Over Temperature and Short Circuit protection. Applications relying on over-current protection require the original Microchip part or design circuit modifications.

Q: Which substitute should be selected for new designs? A: LP3996SD-3033/NOPB is recommended for new designs requiring flexibility, as it offers both 3V and 3.3V output options. LP3996SD-3030/NOPB is suitable for designs with fixed 3V requirements. Both parts are in active production with established supply chains.

Q: How do quiescent current differences affect power consumption? A: The MIC2212-LPYML-TR operates at 80 µA quiescent current versus 100 µA for the LP3996 series. This 20 µA difference is negligible in most applications but may be significant in ultra-low-power standby scenarios.

Q: Can substitutes be used in high-temperature applications? A: No. The LP3996 series maximum operating temperature is 85°C, while the MIC2212-LPYML-TR is rated to 125°C. Applications requiring operation above 85°C must use the original Microchip part.
