Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LP3882EMR-1.2/NOPB is determined by strict alignment of the following critical parameters:

• Fixed output voltage of 1.2V
• Output current rating of 1.5A
• Maximum input voltage of 5.5V
• 8-PowerSOIC package with 0.154" (3.90mm) width
• Surface Mount mounting type
• Operating temperature range of -40°C to 125°C
• Positive output configuration with fixed output type
• Enable control feature and Over Current, Over Temperature, Short Circuit protection

The LP3892EMR-1.2/NOPB qualifies as a parametric equivalent based on these criteria. Both devices share identical output specifications, package geometry, mounting technology, and protection features, enabling direct substitution in applications where the specified electrical and mechanical parameters are required.

Parameter Comparison

Engineering Selection Recommendations

Both the LP3882EMR-1.2/NOPB and LP3892EMR-1.2/NOPB are active production devices suitable for new designs and ongoing production support. Selection between these parts should be based on:

• Availability and lead time requirements
• Voltage dropout performance needs: The LP3882EMR-1.2/NOPB exhibits lower dropout voltage (0.32V) compared to the LP3892EMR-1.2/NOPB (0.55V), which may be critical in applications with limited input voltage headroom
• Compliance requirements: Both devices are ROHS3 compliant and carry EAR99 ECCN classification
• Supply chain strategy and inventory positioning

Frequently Asked Questions (FAQ)

Q: Can the LP3892EMR-1.2/NOPB be used as a direct replacement for the LP3882EMR-1.2/NOPB?

A: Yes, the LP3892EMR-1.2/NOPB is a parametric equivalent. Both devices share identical output voltage, output current, input voltage rating, package geometry, and protection features. The primary difference is voltage dropout specification (0.55V versus 0.32V at 1.5A), which must be evaluated against your specific application requirements.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 8-PowerSOIC package with 0.154" (3.90mm) width and are Surface Mount devices. Pinout and PCB footprint compatibility are maintained.

Q: What is the significance of the voltage dropout difference?

A: Voltage dropout determines the minimum input voltage required to maintain regulation at full output current. The LP3882EMR-1.2/NOPB requires less input voltage headroom due to its lower dropout specification, making it preferable in applications with constrained input voltage margins.

Q: Are both parts suitable for new designs?

A: Yes. Both devices carry Active product status, indicating ongoing manufacturer support and availability for new design implementations.

Q: Do both parts meet RoHS compliance requirements?

A: Yes. Both the LP3882EMR-1.2/NOPB and LP3892EMR-1.2/NOPB are ROHS3 compliant.
