LP3892ES-1.5 Equivalent & Substitute Parts

Part Overview

The LP3892ES-1.5 is a linear voltage regulator IC from Texas Instruments, classified as a Power Management (PMIC) component. It delivers a fixed positive output of 1.5V at 1.5A in a TO-263 (DDPAK-5) surface mount package. The main part number LP3892ES-1.5 is currently listed as obsolete, making identification of equivalent and substitute parts essential for design continuity and procurement planning. Substitute parts maintain identical electrical performance specifications while offering improved product status and compliance certifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the LP3892ES-1.5 are classified based on electrical parameter compatibility and product status. All substitute parts maintain the core electrical specifications: 1.5V fixed output, 1.5A output current, 5.5V maximum input voltage, -40°C to 125°C operating temperature range, and identical package configuration (TO-263-6, DDPAK-5).

Substitution is determined by the following critical parameters:

• Output voltage and current ratings (must match exactly)
• Input voltage range (must support 5.5V maximum)
• Package type and pin configuration (TO-263-6 DDPAK-5)
• Operating temperature range (-40°C to 125°C)
• Control and protection features (Enable function, Over Current, Over Temperature, UVLO)

Variations in voltage dropout, quiescent current, and supply current do not prevent substitution when all primary electrical and mechanical parameters align. Product status and compliance certifications distinguish substitute options for procurement decisions.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts (LP3892ES-1.5/NOPB, LP3882ES-1.5/NOPB, LP38842S-1.5/NOPB) are active products from Texas Instruments and maintain full electrical compatibility with the obsolete LP3892ES-1.5. Selection among substitutes should be based on compliance requirements and product availability.

LP3892ES-1.5/NOPB is the direct equivalent with identical electrical specifications and packaging. It carries ROHS3 compliance and REACH Affected status, making it suitable for applications requiring current regulatory compliance.

LP3882ES-1.5/NOPB offers improved voltage dropout performance (0.27V @ 1.5A versus 0.5V), reducing power dissipation in applications with tight input voltage margins. It maintains ROHS3 compliance and REACH Unaffected status.

LP38842S-1.5/NOPB provides the highest inventory availability and ROHS3 compliance with REACH Unaffected status. The maximum supply current specification is 40 mA compared to 8 mA in other variants; this parameter does not affect substitution compatibility for standard applications.

Frequently Asked Questions (FAQ)

Q: Can LP3892ES-1.5/NOPB directly replace the obsolete LP3892ES-1.5?

A: Yes. LP3892ES-1.5/NOPB is the direct equivalent with identical electrical specifications, output voltage, output current, input voltage range, operating temperature, and TO-263-6 package configuration. The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between LP3882ES-1.5/NOPB and LP3892ES-1.5/NOPB?

A: Both parts deliver 1.5V at 1.5A in the same package. LP3882ES-1.5/NOPB features lower voltage dropout (0.27V @ 1.5A) compared to LP3892ES-1.5/NOPB (0.5V @ 1.5A). This reduces power dissipation and heat generation in applications with limited input voltage headroom. All other electrical parameters remain identical.

Q: Is LP38842S-1.5/NOPB compatible with designs using LP3892ES-1.5?

A: Yes. LP38842S-1.5/NOPB maintains identical output voltage, output current, input voltage range, operating temperature, and package configuration. The maximum supply current specification (40 mA) does not affect substitution compatibility for standard linear regulator applications.

Q: Are all substitute parts RoHS compliant?

A: Yes. All three substitute parts (LP3892ES-1.5/NOPB, LP3882ES-1.5/NOPB, LP38842S-1.5/NOPB) carry ROHS3 compliance certification. The original LP3892ES-1.5 is RoHS non-compliant.

Q: What is the significance of REACH Affected versus REACH Unaffected status?

A: REACH Affected status indicates the part is subject to REACH regulation compliance requirements. REACH Unaffected status indicates the part is not subject to these requirements. Selection depends on end-application regulatory requirements and supply chain compliance policies.

Q: Can these parts be used interchangeably in PCB designs?

A: Yes. All substitute parts use the identical TO-263-6 (DDPAK-5) package with the same pin configuration, footprint, and mechanical dimensions. No PCB layout modifications are required for substitution.

Q: Which substitute part should be selected for new designs?

A: For new designs, select from active products based on compliance requirements and performance needs. LP3892ES-1.5/NOPB provides direct equivalence. LP3882ES-1.5/NOPB offers superior voltage dropout performance. LP38842S-1.5/NOPB provides maximum availability. All three are suitable for production use.
