Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2985-33DBVRM3 are qualified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

• Fixed output voltage of 3.3V
• Maximum input voltage of 16V
• Output current rating of 150mA
• Maximum dropout voltage of 0.575V @ 150mA
• Quiescent current of 95 µA
• SOT-23-5 package configuration
• Operating temperature range of -40°C to 125°C
• Identical control features (Current Limit, Enable)
• Identical protection features (Over Current, Over Temperature, UVLO)
• Active product status
• RoHS3 compliance

The LP2985-33DBVTM3 meets all specified parameters and qualifies as a parametric equivalent within the LP2985 series.

Parameter Comparison

Engineering Selection Recommendations

Both the LP2985-33DBVRM3 and LP2985-33DBVTM3 are Active products with full RoHS3 compliance and REACH unaffected status. The difference between these parts lies in packaging designation: the LP2985-33DBVRM3 is supplied in Tape & Reel (TR) format, while the LP2985-33DBVTM3 is also supplied in Tape & Reel format. Both parts carry identical electrical specifications and protection mechanisms, making them functionally interchangeable in circuit design. Selection between these parts should be based on inventory availability and procurement requirements rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the LP2985-33DBVTM3 replace the LP2985-33DBVRM3 in production?

A: Yes. Both parts are electrically identical with matching output voltage, current rating, dropout voltage, and protection features. The parts differ only in packaging designation within the same Tape & Reel supply format.

Q: Are there any differences in the SOT-23-5 package between these parts?

A: No. Both parts use the SC-74A SOT-753 package designation. The physical footprint and pin configuration are identical.

Q: What is the significance of the part number suffix (M3 vs. M3)?

A: The suffix indicates the specific packaging and tape configuration within Texas Instruments' product line. Both suffixes represent valid supply formats for the same electrical device.

Q: Is the LP2985-33DBVTM3 suitable for the same temperature range applications?

A: Yes. Both parts operate across the identical temperature range of -40°C to 125°C (TJ).

Q: Do both parts have the same regulatory compliance?

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and carry the same ECCN and HTSUS classifications.
