LP2988IMM-5.0/NOPB Equivalent & Substitute Parts

Part Overview

The LP2988IMM-5.0/NOPB is a linear voltage regulator IC manufactured by Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed 5V output at 200mA with a maximum dropout voltage of 0.35V, designed for surface mount applications in 8-VSSOP packaging. The part is Active status and ROHS3 compliant, making it suitable for current production designs. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and regulatory compliance are maintained across the LP2986, LP2987, and LP2988 series variants.

Engineering Selection Recommendations

All substitute parts listed maintain Active product status and ROHS3 compliance, ensuring compatibility with current manufacturing standards and regulatory requirements. Selection among LP2988IMM-5.0/NOPB and its substitutes should be based on availability and inventory levels, as all parts deliver identical electrical performance and mechanical compatibility. The LP2987AIMM-5.0/NOPB and LP2988AIMM-5.0/NOPB variants offer the highest current inventory levels at 3512 and 3487 units respectively. All parts carry MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, supporting long-term storage and supply chain flexibility.

Frequently Asked Questions (FAQ)

Q: Can LP2986AIMM-5.0/NOPB be used as a direct replacement for LP2988IMM-5.0/NOPB?

A: Yes. Both parts maintain identical electrical specifications including 5V fixed output, 200mA current rating, 0.35V dropout voltage, and 8-VSSOP packaging. The difference in base model number (LP2986 vs. LP2988) does not affect functional equivalence when all electrical and mechanical parameters are identical.

Q: What is the difference between the I and A temperature grade suffixes?

A: The I and A suffixes represent different temperature grade designations within the Texas Instruments product line. Both variants operate across the -40°C ~ 125°C temperature range specified in this reference. All electrical parameters remain identical regardless of suffix designation.

Q: Are all substitute parts available in the same 8-VSSOP package?

A: Yes. All parts listed are supplied in 8-VSSOP packaging with identical mechanical dimensions (0.118", 3.00mm Width). Pin configuration and PCB footprint compatibility are maintained across all substitutes.

Q: Do all substitute parts include the same protection features?

A: Yes. All parts include Over Current, Over Temperature, and Short Circuit protection features, along with Enable control functionality. PSRR performance is consistent at 65dB (1kHz) across all variants.

Q: Are there any compliance or regulatory differences between the substitute parts?

A: No. All parts are ROHS3 compliant, REACH Unaffected, carry MSL 1 (Unlimited) moisture sensitivity rating, and maintain Active product status. Regulatory and compliance profiles are identical.
