LP2983AIM5X-1.0 Equivalent & Substitute Parts

Part Overview

The LP2983AIM5X-1.0 is a linear voltage regulator IC from Texas Instruments designed for positive fixed 1V output at 150mA in a SOT-23-5 surface mount package. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. The device provides integrated protection features including over-current, over-temperature, and short-circuit protection, with an enable control feature for power management applications.

Substitute Part Grouping Explanation

Substitute parts for the LP2983AIM5X-1.0 are qualified based on the following critical parameters that determine functional compatibility:

Output voltage: 1V fixed
Output current capability: 150mA
Input voltage range: Maximum 16V
Package type: SOT-23-5 (SC-74A, SOT-753)
Mounting configuration: Surface mount
Control and protection features: Enable control with over-current, over-temperature, and short-circuit protection
Operating temperature range: -40°C ~ 125°C
Quiescent current: 95 µA
PSRR: 65dB (1kHz)

Parts meeting all these electrical and mechanical parameters are classified as direct substitutes. Variations in product status, packaging format (bulk vs. tape & reel), and compliance certifications do not affect functional equivalence.

Engineering Selection Recommendations

LP2983AIM5X-1.0/NOPB is the primary substitute for the obsolete LP2983AIM5X-1.0. This part maintains identical electrical specifications and package configuration while offering active product status and ROHS3 compliance. The /NOPB designation indicates lead-free manufacturing, aligning with current environmental and regulatory standards.

LP2983IM5X-1.0/NOPB provides parametric equivalence with identical electrical performance and package type. This part is also obsolete but remains available in limited inventory. Both substitute parts are functionally interchangeable with the original LP2983AIM5X-1.0 for applications requiring 1V fixed output at 150mA in SOT-23-5 packaging.

For new designs or long-term procurement, LP2983AIM5X-1.0/NOPB is the recommended selection due to active product status and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can LP2983AIM5X-1.0/NOPB be used as a direct replacement for LP2983AIM5X-1.0?

A: Yes. Both parts share identical electrical specifications including 1V fixed output, 150mA output current, 16V maximum input voltage, 95 µA quiescent current, and 65dB PSRR at 1kHz. The package type (SOT-23-5) and mounting configuration are identical. The primary difference is product status and compliance certification.

Q: What is the difference between LP2983AIM5X-1.0 and LP2983IM5X-1.0/NOPB?

A: Both parts are parametrically equivalent with identical electrical performance and SOT-23-5 packaging. The difference lies in product status (both obsolete) and compliance certifications. Both are suitable for applications requiring 1V fixed output at 150mA.

Q: Does the /NOPB designation affect compatibility?

A: No. The /NOPB designation indicates lead-free (no lead/no plumbum) manufacturing and does not affect electrical performance or package compatibility. It reflects manufacturing process compliance with environmental standards.

Q: Are there any packaging format differences between these parts?

A: The main part (LP2983AIM5X-1.0) is listed without specified packaging format. LP2983AIM5X-1.0/NOPB is available in Tape & Reel (TR) format. LP2983IM5X-1.0/NOPB packaging format is not specified. All three parts use the same SOT-23-5 package type and are surface mount components.

Q: What compliance certifications apply to these parts?

A: LP2983AIM5X-1.0 is RoHS non-compliant. LP2983AIM5X-1.0/NOPB and LP2983IM5X-1.0/NOPB are both ROHS3 compliant. All three parts are REACH unaffected and classified under ECCN EAR99.
