LP2986AIM-3.0 Equivalent & Substitute Parts

Part Overview

The LP2986AIM-3.0 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. This device delivers a fixed 3V output at 200mA with a maximum dropout voltage of 0.35V, designed for low-power applications requiring stable voltage regulation. The part is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement capability.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP2986AIM-3.0 are classified based on electrical parameter equivalence and mechanical compatibility. All identified substitutes maintain the following critical specifications: fixed 3V output voltage, 200mA output current capability, 16V maximum input voltage, 0.35V maximum dropout voltage at 200mA, 120 µA quiescent current, and 8-SOIC package configuration. These parameters define the functional interchangeability boundary for this linear regulator category. Substitutes are grouped into two categories: direct manufacturer equivalents (identical part number variants) and parametric equivalents (different base part numbers with matching electrical performance).

Parameter Comparison

Engineering Selection Recommendations

The LP2986AIM-3.0 is obsolete; active alternatives are available with identical electrical and mechanical specifications. LP2986AIM-3.0/NOPB (National Semiconductor) and LP2986IM-3.0/NOPB (Texas Instruments) are direct functional equivalents with active product status. LP2986IM-3.0/NOPB carries RoHS3 compliance certification, whereas the original part is RoHS non-compliant. LP2987IM-3.0/NOPB (National Semiconductor) provides equivalent performance with active status. All substitutes are surface-mount 8-SOIC packages with identical electrical performance parameters. Selection should prioritize active-status parts to ensure long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can LP2986IM-3.0/NOPB directly replace LP2986AIM-3.0? A: Yes. Both parts deliver 3V fixed output at 200mA with identical dropout voltage, quiescent current, and 8-SOIC package configuration. The primary difference is product status: LP2986IM-3.0/NOPB is active while LP2986AIM-3.0 is obsolete.

Q: What is the difference between LP2986AIM-3.0/NOPB and LP2987IM-3.0/NOPB? A: Both are parametric equivalents with identical electrical specifications and 8-SOIC packaging. The base part number differs (LP2986 vs. LP2987), but functional performance is equivalent for this 3V, 200mA application.

Q: Does RoHS compliance affect substitution compatibility? A: RoHS compliance does not affect electrical or mechanical compatibility. LP2986IM-3.0/NOPB is RoHS3 compliant while the original LP2986AIM-3.0 is non-compliant. Selection depends on application regulatory requirements.

Q: Are all substitutes available in the same packaging? A: Yes. All substitute parts use 8-SOIC (0.154", 3.90mm Width) surface-mount packaging, ensuring mechanical compatibility with existing PCB layouts.

Q: What protection features are included in substitute parts? A: All substitute parts include over-current, over-temperature, and short-circuit protection, matching the original LP2986AIM-3.0 specifications.
