Key Parameters

Substitute Part Grouping Explanation

Substitution for the LP3882EMRX-1.2 is determined by the following critical parameters:

• Output voltage specification (1.2V fixed)
• Maximum output current capability (1.5A)
• Package compatibility (8-PowerSOIC)
• Voltage dropout performance
• Operating temperature range (-40°C ~ 125°C)
• Surface mount configuration

Two substitute parts meet these criteria with varying compliance and packaging options. Both maintain identical electrical output specifications and package form factor, ensuring direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

LP3882EMRX-1.2/NOPB is the direct equivalent substitute. This part maintains identical electrical specifications including the 0.32V maximum dropout voltage and is available in active production status with ROHS3 compliance. The Tape & Reel packaging provides standard manufacturing compatibility.

LP3892EMRX-1.2/NOPB serves as a parametric equivalent with the same output voltage, current rating, and package form factor. The primary difference is an increased maximum dropout voltage of 0.55V at 1.5A compared to 0.32V. This part is suitable for applications where the higher dropout voltage does not impact system performance. ROHS3 compliance and active production status apply to this variant as well.

For designs requiring the lowest dropout voltage specification, LP3882EMRX-1.2/NOPB is the appropriate selection. For applications with less stringent dropout requirements, LP3892EMRX-1.2/NOPB offers an alternative with equivalent current delivery and thermal performance.

Frequently Asked Questions (FAQ)

Q: Can LP3882EMRX-1.2/NOPB directly replace the obsolete LP3882EMRX-1.2?

A: Yes. LP3882EMRX-1.2/NOPB is a direct equivalent with identical electrical specifications, output voltage, current rating, and package configuration. The primary difference is active production status and ROHS3 compliance.

Q: What is the key difference between LP3882EMRX-1.2/NOPB and LP3892EMRX-1.2/NOPB?

A: Both parts deliver 1.2V at 1.5A in the same 8-PowerSOIC package. The LP3892EMRX-1.2/NOPB has a maximum dropout voltage of 0.55V at 1.5A, compared to 0.32V for the LP3882EMRX-1.2/NOPB. All other electrical parameters remain identical.

Q: Are the packaging options interchangeable?

A: Yes. Both substitute parts use the 8-PowerSOIC (0.154", 3.90mm Width) package. Tape & Reel and Cut Tape packaging options are manufacturing formats for the same physical component and are interchangeable in circuit design.

Q: Does the higher dropout voltage of LP3892EMRX-1.2/NOPB affect circuit performance?

A: Dropout voltage impact depends on your input voltage margin and load current requirements. At 1.5A output, the LP3892 requires an additional 0.23V of input headroom compared to the LP3882. Verify your power supply voltage can accommodate this difference.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both LP3882EMRX-1.2/NOPB and LP3892EMRX-1.2/NOPB are ROHS3 compliant, whereas the original LP3882EMRX-1.2 is RoHS non-compliant.
