LP3907TLX-PLNTO/NOPB Equivalent & Substitute Parts

Part Overview

The LP3907TLX-PLNTO/NOPB is a quad-output power management IC (PMIC) manufactured by Texas Instruments, designed for linear switching voltage regulation applications. This device integrates two synchronous step-down (buck) regulators and two linear (LDO) regulators in a single 25-uSMD package, operating at 2.1MHz switching frequency with a supply voltage range of 2.8V to 5.5V.

The LP3907TLX-PLNTO/NOPB 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 utilizing this component.

Substitute Part Grouping Explanation

Substitute parts for the LP3907TLX-PLNTO/NOPB are identified based on strict electrical and mechanical parameter matching. The critical parameters that determine substitution eligibility are:

• Base product number (LP3907 series)
• Topology configuration (2 synchronous buck + 2 LDO outputs)
• Number of outputs (4)
• Switching frequency (2.1MHz)
• Output voltage and current specifications (1.3V/1A, 2.2V/600mA, 2.9V/300mA)
• Supply voltage range (2.8V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Package type (25-WFBGA)
• Compliance certifications (ROHS3, REACH Unaffected)

Substitute parts must match all electrical specifications and package requirements to ensure functional and mechanical compatibility with existing designs.

Parameter Comparison

Engineering Selection Recommendations

The LP3907TL-PLNTO/NOPB is a direct functional equivalent to the LP3907TLX-PLNTO/NOPB. Both parts share identical electrical specifications, output configurations, and package geometry. The primary distinction is product status: the LP3907TLX-PLNTO/NOPB is classified as Obsolete, while the LP3907TL-PLNTO/NOPB maintains Active status.

For new designs or ongoing production requiring quad-output PMIC functionality with the specified electrical characteristics, the LP3907TL-PLNTO/NOPB is the appropriate selection. Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for electronic component applications.

The packaging difference (Tube versus Tape & Reel) reflects standard distribution formats and does not affect electrical or mechanical compatibility. Component selection should be based on supply chain availability and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the LP3907TL-PLNTO/NOPB be used as a direct replacement for the LP3907TLX-PLNTO/NOPB?

A: Yes. Both parts are electrically and mechanically identical. They share the same base product number (LP3907), topology configuration, output specifications, supply voltage range, switching frequency, operating temperature range, and 25-WFBGA package. No design modifications are required for substitution.

Q: What is the significance of the product status difference?

A: The LP3907TLX-PLNTO/NOPB is classified as Obsolete, indicating Texas Instruments has discontinued active production and support. The LP3907TL-PLNTO/NOPB maintains Active status, ensuring ongoing availability, technical support, and compliance with current manufacturing standards.

Q: Are there packaging compatibility considerations?

A: The LP3907TLX-PLNTO/NOPB is supplied in Tube packaging, while the LP3907TL-PLNTO/NOPB is supplied in Tape & Reel (TR) format. Both formats contain identical components in the same 25-WFBGA package. Packaging format selection depends on procurement volume and assembly line requirements, not component functionality.

Q: Do both parts meet the same regulatory compliance standards?

A: Yes. Both the LP3907TLX-PLNTO/NOPB and LP3907TL-PLNTO/NOPB are ROHS3 Compliant and REACH Unaffected. They satisfy equivalent regulatory requirements for electronic component applications.

Q: What parameters must match for a part to be considered a valid substitute?

A: Valid substitutes must match all electrical specifications including topology (2 synchronous buck + 2 LDO), number of outputs (4), switching frequency (2.1MHz), output voltage and current ratings (1.3V/1A, 2.2V/600mA, 2.9V/300mA), supply voltage range (2.8V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (25-WFBGA). Compliance certifications must also be equivalent.
