LP2988IMMX-5.0 Equivalent & Substitute Parts

Part Overview

The LP2988IMMX-5.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 5V output applications with 200mA current capacity in an 8-VSSOP surface mount package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing production and design requirements. Active alternatives from the LP2986, LP2987, and LP2988 series provide identical electrical and mechanical specifications with current product status and improved compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2988IMMX-5.0 are qualified based on strict electrical and mechanical parameter matching:

Qualifying Criteria:

• Fixed 5V output voltage
• 200mA output current capacity
• 16V maximum input voltage
• 0.35V maximum dropout voltage at 200mA
• 120 µA quiescent current
• 65dB PSRR at 1kHz
• -40°C to 125°C operating temperature range
• 8-VSSOP package configuration
• Enable control feature
• Over Current, Over Temperature, and Short Circuit protection

All substitute parts meet these parameters identically. The primary distinction between the main part and substitutes is product status: LP2988IMMX-5.0 is obsolete, while all listed substitutes maintain active product status. Secondary differences include RoHS compliance certification and packaging format (Tape & Reel for substitutes versus unspecified for the main part).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts provide direct functional equivalence to the LP2988IMMX-5.0. Selection should prioritize active product status and compliance certifications:

Primary Selection Criteria:

• All substitutes carry ROHS3 compliance, addressing regulatory requirements absent in the obsolete main part
• All substitutes maintain active product status, ensuring long-term availability and supply chain stability
• Packaging format differences (Tape & Reel for substitutes) align with standard manufacturing practices

Inventory Availability: LP2986IMM-5.0/NOPB offers the highest inventory level at 29,400 pieces, providing supply security for high-volume applications. LP2986AIMMX-5.0/NOPB provides 4,400 pieces with extended temperature performance designation. Remaining substitutes maintain adequate stock levels between 1,900 and 3,512 pieces.

Compliance Considerations: The transition from the non-compliant LP2988IMMX-5.0 to ROHS3-compliant alternatives aligns with current manufacturing and environmental standards. All substitutes carry identical REACH Unaffected and EAR99 ECCN classifications.

Frequently Asked Questions (FAQ)

Q: Can LP2986 series parts directly replace LP2988IMMX-5.0? A: Yes. LP2986AIMM-5.0/NOPB, LP2986AIMMX-5.0/NOPB, LP2986IMM-5.0/NOPB, and LP2986IMMX-5.0/NOPB provide identical electrical specifications, output voltage, current capacity, dropout voltage, and package configuration. The primary advantage is active product status and ROHS3 compliance.

Q: What is the difference between LP2986, LP2987, and LP2988 base series? A: All three base series (LP2986, LP2987, LP2988) deliver identical electrical and mechanical parameters for the 5V 200mA configuration specified. Differences exist only in product lifecycle status and manufacturing designations. Selection between series should be based on inventory availability and supply chain requirements.

Q: Does the "IMM" versus "AIMM" designation affect compatibility? A: No. Both IMM and AIMM variants meet the specified electrical parameters. The designations reflect internal manufacturing or temperature performance classifications but do not alter functional equivalence for this 5V 200mA regulator application.

Q: Are the "X" variants (IMMX, AIMMX) interchangeable with non-X variants? A: Yes. Parts designated with "X" (such as LP2986AIMMX-5.0/NOPB versus LP2986AIMM-5.0/NOPB) maintain identical electrical specifications and package configuration. The "X" designation does not indicate functional differences relevant to substitution.

Q: What packaging format should I specify for new designs? A: All substitute parts are supplied in Tape & Reel (TR) format, which is standard for surface mount production. This format is compatible with automated assembly equipment and provides better handling characteristics than the unspecified packaging of the obsolete main part.

Q: Is the 8-VSSOP package identical across all parts? A: Yes. All parts use the 8-VSSOP package with 0.118" (3.00mm) width. This package is also referenced as 8-TSSOP or 8-MSOP. PCB footprints and thermal characteristics are identical across all listed parts.

Q: Why should I transition away from LP2988IMMX-5.0? A: The LP2988IMMX-5.0 is classified as obsolete, creating long-term supply and support risks. Active alternatives provide identical functionality with ROHS3 compliance, improved regulatory alignment, and guaranteed availability through established distribution channels.
