LP2987IM-3.3/NOPB Equivalent & Substitute Parts

Part Overview

The LP2987IM-3.3/NOPB is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed 3.3V output at 200mA with a maximum dropout voltage of 0.35V, designed for surface mount applications in 8-SOIC packaging. The part is currently in active production status with 2300 units available in inventory. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the same product category and packaging specification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2987IM-3.3/NOPB are identified based on strict parametric equivalence across the following critical specifications:

• Fixed output voltage of 3.3V
• Output current rating of 200mA
• Maximum input voltage of 16V
• Dropout voltage of 0.35V @ 200mA
• 8-SOIC surface mount package (0.154", 3.90mm Width)
• Operating temperature range of -40°C ~ 125°C
• Enable control feature
• Protection features: Over Current, Over Temperature, Short Circuit
• PSRR of 65dB (1kHz)
• Quiescent current of 120 µA
• Active product status
• ROHS3 compliance

The LP2986IM-3.3/NOPB and LP2986AIM-3.3/NOPB meet all these parameters and are therefore classified as parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

All three parts—LP2987IM-3.3/NOPB, LP2986IM-3.3/NOPB, and LP2986AIM-3.3/NOPB—maintain active product status with Texas Instruments and carry ROHS3 compliance certification. The LP2987IM-3.3/NOPB has the highest current inventory at 2300 units. The LP2986IM-3.3/NOPB provides 1498 units in stock, while the LP2986AIM-3.3/NOPB offers 1108 units. Selection between these parts should be based on availability requirements and supply chain considerations, as all electrical and mechanical parameters are identical.

Frequently Asked Questions (FAQ)

Q: Can LP2986IM-3.3/NOPB and LP2986AIM-3.3/NOPB be used interchangeably with LP2987IM-3.3/NOPB?

A: Yes. All three parts share identical electrical specifications including output voltage, current rating, dropout voltage, quiescent current, PSRR, and protection features. They are packaged in the same 8-SOIC form factor with identical pin configurations and operating temperature ranges.

Q: Are there any differences in the package or mounting requirements?

A: No. All three parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package with identical mechanical dimensions and PCB footprint requirements.

Q: What compliance certifications apply to all substitute parts?

A: All parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited). They carry identical REACH and ECCN classifications.

Q: How do I determine which part to order if all are equivalent?

A: Selection should be based on inventory availability and supply chain lead times. The LP2987IM-3.3/NOPB has the highest stock level at 2300 units, followed by LP2986IM-3.3/NOPB at 1498 units and LP2986AIM-3.3/NOPB at 1108 units.

Q: Are there any temperature or environmental limitations that differ between these parts?

A: No. All three parts operate across the identical temperature range of -40°C to 125°C with the same protection features for over-current, over-temperature, and short-circuit conditions.
