Key Parameters

Substitute Part Grouping Explanation

Substitution of the LP2986AIMX-3.0 is determined by strict alignment of the following electrical and mechanical parameters:

• Output voltage specification: 3V fixed output
• Output current capability: 200mA minimum
• Input voltage tolerance: 16V maximum
• Voltage dropout performance: 0.35V @ 200mA
• Quiescent current: 120 µA
• PSRR performance: 65dB (1kHz)
• Protection features: Over Current, Over Temperature, Short Circuit
• Package compatibility: 8-SOIC form factor
• Operating temperature range: -40°C ~ 125°C
• Control features: Enable function

The LP2987IMX-3.0/NOPB meets all specified electrical parameters and maintains identical package geometry, making it a direct parametric equivalent. The primary distinction is product status: the LP2987IMX-3.0/NOPB is active production, whereas the LP2986AIMX-3.0 is obsolete.
