LP2987AIMX-5.0 Equivalent & Substitute Parts

Part Overview

The LP2987AIMX-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output at 200mA capacity. This device is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing design support and procurement. The part operates across -40°C to 125°C and includes integrated protection features for over-current, over-temperature, and short-circuit conditions. Substitute parts must maintain identical electrical performance and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2987AIMX-5.0 are classified based on electrical parameter equivalence and product status. All substitute candidates maintain identical specifications across the following critical parameters: output voltage (5V fixed), output current (200mA), input voltage rating (16V maximum), dropout voltage (0.35V @ 200mA), quiescent current (120 µA), PSRR (65dB at 1kHz), operating temperature range (-40°C to 125°C), package type (8-SOIC), and protection features (over-current, over-temperature, short-circuit).

Substitutes are further differentiated by product status (active versus obsolete), manufacturer designation, and compliance certifications. The LP2987AIMX-5.0/NOPB represents a direct manufacturer equivalent with active product status. The LP2986 and LP2988 series parts are parametric equivalents that satisfy all electrical and mechanical requirements while offering improved availability and compliance status.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain complete electrical and mechanical equivalence to the LP2987AIMX-5.0. Selection among active alternatives should prioritize product status and compliance requirements.

The LP2987AIMX-5.0/NOPB is the direct manufacturer equivalent with active product status, offering the most straightforward replacement path. The LP2986IMX-5.0/NOPB and LP2988IMX-5.0/NOPB variants from Texas Instruments provide ROHS3 compliance certification, which may be required for applications subject to RoHS regulations. The LP2986AIMX-5.0/NOPB and LP2987IMX-5.0/NOPB from National Semiconductor are active alternatives with equivalent electrical performance.

Packaging considerations apply to procurement workflows: Tape & Reel (TR) packaging is suitable for automated assembly processes, while Bulk packaging accommodates manual or mixed assembly environments. All parts are classified as REACH Unaffected and carry EAR99 export classification.

Frequently Asked Questions (FAQ)

Q: Can LP2987AIMX-5.0 be directly replaced with LP2987AIMX-5.0/NOPB?

A: Yes. The LP2987AIMX-5.0/NOPB is the direct manufacturer equivalent with identical electrical specifications, output voltage (5V), output current (200mA), dropout voltage (0.35V @ 200mA), and 8-SOIC package. The primary difference is active product status versus obsolete classification.

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

A: Both series maintain identical electrical parameters and package specifications. The distinction lies in product designation and manufacturer sourcing. All variants listed satisfy the same functional requirements for 5V, 200mA linear regulation with 0.35V dropout voltage.

Q: Are LP2986IMX-5.0/NOPB and LP2988IMX-5.0/NOPB interchangeable with the original part?

A: Yes. These parts are parametric equivalents with identical electrical performance across all critical specifications: output voltage, current rating, dropout voltage, quiescent current, PSRR, operating temperature range, and protection features. The 8-SOIC package ensures mechanical compatibility.

Q: Does packaging type (Bulk versus Tape & Reel) affect electrical performance?

A: No. Packaging type affects procurement and assembly logistics only. Electrical specifications remain identical regardless of packaging format. Selection should align with manufacturing process requirements.

Q: Which substitute offers the best compliance status?

A: LP2986IMX-5.0/NOPB and LP2988IMX-5.0/NOPB both carry ROHS3 compliance certification. These parts are recommended for applications requiring RoHS regulatory compliance. All listed substitutes are REACH Unaffected.

Q: Can these parts be used in high-temperature applications?

A: Yes. All listed parts, including the original LP2987AIMX-5.0, operate across the -40°C to 125°C temperature range with integrated over-temperature protection.
