LP2987IMM-5.0 Equivalent & Substitute Parts

Part Overview

The LP2987IMM-5.0 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed 5V positive output at 200mA with a maximum dropout voltage of 0.35V at full load current. The part features integrated over-current, over-temperature, and short-circuit protection, along with an enable control function.

The LP2987IMM-5.0 is currently listed as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Active alternatives with identical electrical and mechanical specifications are available from the same manufacturer.

Substitute Part Grouping Explanation

Substitution eligibility for the LP2987IMM-5.0 is determined by strict equivalence across the following critical parameters:

Output voltage: 5V fixed
Output current capability: 200mA
Input voltage rating: 16V maximum
Dropout voltage: 0.35V @ 200mA
Package type: 8-VSSOP
Protection features: Over-current, over-temperature, short-circuit
Operating temperature range: -40°C to 125°C
Control features: Enable function

All substitute parts listed maintain identical electrical performance and mechanical compatibility. Differences exist only in product status (active vs. obsolete), RoHS compliance level, and packaging format (bulk vs. tape & reel).

Engineering Selection Recommendations

All listed substitute parts are electrically and mechanically equivalent to the LP2987IMM-5.0. Selection among these alternatives should be based on the following factors:

Product Status: The original LP2987IMM-5.0 is obsolete. All substitute parts listed are active products, ensuring long-term availability and continued manufacturer support.

Compliance Requirements: The LP2987IMM-5.0 is RoHS non-compliant. All substitute parts are RoHS3 compliant, meeting current environmental and regulatory standards for new designs and production.

Packaging Format: The original part is supplied in bulk. Substitute parts are available in tape & reel (TR) format, which is standard for automated assembly processes.

Inventory Availability: LP2986IMM-5.0/NOPB offers the highest inventory level at 29,400 units, followed by LP2986AIMMX-5.0/NOPB at 4,400 units. Other alternatives range from 1,900 to 3,512 units.

For new designs or production transitions, LP2987IMM-5.0/NOPB or LP2987AIMM-5.0/NOPB maintain the same base product number as the original part. For maximum availability, LP2986IMM-5.0/NOPB is the preferred alternative.

Frequently Asked Questions (FAQ)

Q: Are all listed parts pin-for-pin compatible with the LP2987IMM-5.0?

A: Yes. All substitute parts use the 8-VSSOP package with identical pinout, electrical characteristics, and functional specifications. Direct replacement is possible without circuit modification.

Q: What is the difference between LP2986 and LP2987 series parts?

A: Both series deliver identical electrical performance for this 5V 200mA application. The difference lies in the base product number designation assigned by Texas Instruments. All variants listed are functionally equivalent.

Q: Why do some part numbers include "/NOPB" suffix?

A: The "/NOPB" suffix indicates "No Plumbum" (lead-free) construction, confirming RoHS3 compliance. This is standard for active production parts.

Q: What is the difference between IMM and IMMX packaging designations?

A: Both designations refer to 8-VSSOP surface-mount packages with identical mechanical and electrical specifications. The "X" suffix may indicate extended temperature range or manufacturing process variation, but electrical performance remains identical.

Q: Can I use the LP2986 series as a substitute for LP2987 series?

A: Yes. Both LP2986 and LP2987 series parts listed are parametrically equivalent for this 5V 200mA application. Selection can be based on inventory availability and compliance requirements.

Q: Is the original LP2987IMM-5.0 still available?

A: The LP2987IMM-5.0 is listed as obsolete but 13,500 units remain in inventory. However, for new production, active alternatives are recommended to ensure long-term supply continuity.

Q: Do all parts have the same protection features?

A: Yes. All listed parts include over-current, over-temperature, and short-circuit protection with identical enable control functionality.
