LP2989IM-3.3/NOPB Equivalent & Substitute Parts Reference

Part Overview

The LP2989IM-3.3/NOPB from Texas Instruments is a Power Management IC (PMIC), specifically a linear voltage regulator. It provides a fixed 3.3V output, supports up to 500mA of current, and incorporates standard protection features such as over current, over temperature, and short circuit protection. This model is supplied in an 8-SOIC surface-mount package. The part is currently active and RoHS3 compliant.

Sourcing alternative models is necessary to ensure continuous design flexibility, mitigate supply chain risks, and facilitate direct replacements in case primary sources become unavailable or reach allocation limits. Equivalent substitutes must match or exceed the specified critical electrical, mechanical, and compliance characteristics.

Key Parameters

Substitute Part Grouping Explanation

The selection of equivalent and substitute linear voltage regulator ICs for the LP2989IM-3.3/NOPB is based strictly on matching the following parameters: output voltage (fixed 3.3V), maximum output current (500mA), output configuration (positive), type (fixed), number of outputs (1), voltage dropout, maximum input voltage, control features (enable), protection features, operating temperature, package, and compliance (RoHS3, REACH). Only parts matching these characteristics within the declared category and mechanical constraints are listed as equivalents.

Key parameters used for substitution:

• Output voltage (3.3V fixed)
• Output current (500mA)
• Output configuration/type
• Number of regulators (1)
• Mounting type and package
• Maximum input voltage
• Voltage dropout@500mA
• Compliance certifications (RoHS3, REACH)
• Operating temperature range
• Protection features
• Control features

Parameter Comparison

Engineering Selection Recommendations

All listed substitute linear voltage regulator ICs are active and compliant with RoHS3 and REACH requirements. Both substitute parts, TPS7A2633DRVR and AP2213M-3.3TRG1, hold an ECCN code of EAR99, indicating export regulatory parity with LP2989IM-3.3/NOPB. Moisture Sensitivity Levels vary, with the AP2213M-3.3TRG1 possessing an MSL of 3 (168 hours), while the primary and TPS7A2633DRVR substitutes are rated MSL 1 (unlimited). Package type should be matched according to mechanical and assembly requirements.

Frequently Asked Questions (FAQ)

Q: What are the critical criteria for considering a linear voltage regulator IC equivalent?
A: Output voltage, output current capability, output configuration and type, maximum input voltage, voltage dropout, number of regulators, package type, control/protection features, operating temperature range, and compliance status.

Q: Do all listed substitutes provide the same package as the LP2989IM-3.3/NOPB?
A: AP2213M-3.3TRG1 matches the 8-SOIC package of the LP2989IM-3.3/NOPB. TPS7A2633DRVR is supplied in a 6-WSON (2x2mm) package.

Q: Is there any difference in environmental and export certifications among these parts?
A: All listed parts are RoHS3 compliant, REACH unaffected, and share the ECCN code EAR99.

Q: Are there differences in Moisture Sensitivity Level (MSL)?
A: Yes. LP2989IM-3.3/NOPB and TPS7A2633DRVR are MSL 1 (unlimited), while AP2213M-3.3TRG1 is MSL 3 (168 hours).

Q: Are additional features present in substitutes relevant for equivalency?
A: Only the parameters explicitly listed, such as output voltage, current, protection features, and compliance, are considered for equivalency in this reference. Any extra features are not included in substitution criteria.
