LP2988IMM-5.0 Equivalent & Substitute Parts

Part Overview

The LP2988IMM-5.0 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive 5V output at 200mA with a maximum dropout voltage of 0.35V at full load. The device integrates over-current, over-temperature, and short-circuit protection, making it suitable for low-power regulated supply applications requiring compact surface-mount packaging.

The LP2988IMM-5.0 carries a Last Time Buy product status, indicating limited availability. Identifying equivalent and substitute parts ensures design continuity and supply chain flexibility for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2988IMM-5.0 are qualified based on identical electrical and mechanical parameters across all critical specifications. The substitution logic is structured as follows:

Primary Substitution Criteria:

• Fixed output voltage: 5V
• Output current capacity: 200mA
• Maximum input voltage: 16V
• Dropout voltage: 0.35V @ 200mA
• Quiescent current: 120 µA
• PSRR: 65dB (1kHz)
• Protection features: Over Current, Over Temperature, Short Circuit
• Operating temperature range: -40°C to 125°C
• Package type: 8-VSSOP
• RoHS3 compliance and MSL 1 rating

Packaging Variants: Substitutes include both Cut Tape (CT) and Tape & Reel (TR) packaging options. The LP2988IMM-5.0/NOPB represents the direct equivalent in Tape & Reel format. The LP2986 and LP2987 series variants (AIMM, IMM, AIMMX, IMMX suffixes) are parametrically equivalent, differing only in manufacturing lot codes and packaging reels, not in electrical performance or physical dimensions.

All listed substitutes maintain identical electrical specifications, thermal performance, and protection characteristics, enabling direct replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain identical electrical and mechanical specifications to the LP2988IMM-5.0. Selection should prioritize the following factors:

Product Status: The LP2988IMM-5.0 carries Last Time Buy status. All substitute parts listed carry Active product status, ensuring long-term availability and continued manufacturing support from Texas Instruments.

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. These options provide the greatest supply security for volume production.

Compliance & Certifications: All parts maintain ROHS3 compliance, REACH unaffected status, and MSL 1 (unlimited) moisture sensitivity rating. No compliance trade-offs exist between the main part and substitutes.

Packaging Format: The original LP2988IMM-5.0 is supplied in Cut Tape format. Direct equivalents in Tape & Reel format (LP2988IMM-5.0/NOPB, LP2988AIMM-5.0/NOPB) are available for automated assembly processes. Parametric equivalents from the LP2986 and LP2987 series are supplied exclusively in Tape & Reel format.

For new designs or high-volume production, LP2986IMM-5.0/NOPB is recommended due to superior inventory availability and Active product status.

Frequently Asked Questions (FAQ)

Q: Can LP2986 and LP2987 series parts directly replace LP2988IMM-5.0 in existing designs?

A: Yes. All listed substitutes are parametrically equivalent, sharing identical output voltage (5V), output current (200mA), dropout voltage (0.35V @ 200mA), quiescent current (120 µA), PSRR (65dB at 1kHz), protection features, and 8-VSSOP package dimensions. No circuit modifications are required.

Q: What is the difference between LP2988IMM-5.0 and LP2988IMM-5.0/NOPB?

A: The /NOPB suffix indicates "No Plumbum" (lead-free) packaging supplied in Tape & Reel format. The LP2988IMM-5.0 is supplied in Cut Tape format. Both are electrically and mechanically identical and fully interchangeable.

Q: Why do LP2986 and LP2987 variants have different part numbers if they are equivalent?

A: Part number variations (AIMM, IMM, AIMMX, IMMX suffixes) represent different manufacturing lots and tape reel configurations. These designations do not affect electrical performance or physical dimensions. All variants meet identical specifications for voltage regulation, current delivery, thermal performance, and protection features.

Q: Is the 8-VSSOP package identical across all substitute parts?

A: Yes. All parts use the 8-VSSOP package with identical physical dimensions (0.118" / 3.00mm width). The package is also referenced as 8-TSSOP or 8-MSOP in technical documentation. PCB footprints and component placement are identical across all substitutes.

Q: Which substitute part offers the best supply availability?

A: LP2986IMM-5.0/NOPB provides the highest inventory at 29,400 units. This part is recommended for designs requiring immediate procurement or high-volume production quantities.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (unlimited) moisture sensitivity rating, matching the original LP2988IMM-5.0 specifications.
