Substitute Part Grouping Explanation

Substitution is strictly determined by alignment of all functional and mechanical parameters between the main part (LP2988AIM-5.0) and its equivalents. Direct and parametric equivalents must match in output configuration, output type, output voltage, dropout voltage, output current capability, control features, protection mechanisms, package type, compliance status, temperature range, and mounting style. No deviation or inference from the provided explicit parameters is permitted.
