LP3892EMRX-1.5 Equivalent & Substitute Parts

Part Overview

The LP3892EMRX-1.5 is a linear voltage regulator IC from Texas Instruments designed for positive fixed output applications. It delivers 1.5A output current with a fixed 1.5V output and operates across an input voltage range up to 5.5V. The device integrates protection features including over-current, over-temperature, and under-voltage lockout (UVLO) protection, making it suitable for power management applications requiring regulated low-voltage outputs.

The main part number LP3892EMRX-1.5 carries an Obsolete product status. Identifying equivalent substitute parts is necessary to ensure design continuity, maintain supply chain reliability, and support ongoing production requirements for applications currently using this regulator.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP3892EMRX-1.5 are identified based on strict electrical and mechanical parameter matching:

Critical Matching Parameters:

• Output voltage: 1.5V fixed
• Output current capability: 1.5A
• Maximum input voltage: 5.5V
• Dropout voltage: 0.55V @ 1.5A
• Package: 8-PowerSOIC (0.154", 3.90mm Width)
• Protection features: Over Current, Over Temperature, UVLO
• Operating temperature range: -40°C to 125°C

The LP3892EMRX-1.5/NOPB qualifies as a direct substitute, maintaining identical electrical specifications and mechanical compatibility while differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The LP3892EMRX-1.5/NOPB is the direct equivalent substitute for the obsolete LP3892EMRX-1.5. Both parts share identical electrical performance and mechanical compatibility, with the substitute offering the advantage of Active product status and ROHS3 compliance. The primary difference is packaging format: the substitute is supplied in Tape & Reel configuration, which is standard for production environments, whereas the original part was supplied in bulk packaging.

For new designs or production transitions, the LP3892EMRX-1.5/NOPB is the appropriate selection. Existing designs using the LP3892EMRX-1.5 can transition to this substitute without circuit modification or re-qualification, provided that the Tape & Reel packaging format is compatible with assembly processes.

Frequently Asked Questions (FAQ)

Q: Can LP3892EMRX-1.5/NOPB be used as a direct replacement for LP3892EMRX-1.5?

A: Yes. Both parts are electrically and mechanically identical. They deliver the same 1.5V output at 1.5A, operate across the same input voltage range (up to 5.5V), and are housed in the same 8-PowerSOIC package. The substitute is the active production equivalent.

Q: What is the difference between these two part numbers?

A: The primary differences are product status and packaging format. LP3892EMRX-1.5 is Obsolete and supplied in bulk; LP3892EMRX-1.5/NOPB is Active and supplied in Tape & Reel. The "/NOPB" suffix indicates Tape & Reel packaging without plating on leads. Additionally, the substitute meets ROHS3 compliance, whereas the original does not.

Q: Are there any circuit design changes required when switching to LP3892EMRX-1.5/NOPB?

A: No circuit design changes are required. The electrical specifications, pin configuration, and functional behavior are identical. The transition is a direct substitution at the component level.

Q: Does the Tape & Reel packaging affect PCB assembly compatibility?

A: No. Tape & Reel packaging is standard for automated assembly processes and is compatible with pick-and-place equipment. The component itself is identical; only the delivery format differs.

Q: What is the MSL (Moisture Sensitivity Level) for both parts?

A: Both parts have MSL 3 with a floor life of 168 hours. Standard moisture control procedures during storage and assembly apply.
